Students will: conduct research collaboratively with institutional and industrial partners, receive hands-on technical training in nanotechnology, develop project management skills, cultivate an entrepreneurial spirit, receive travel opportunities and career support, and more. Applications and Opportunities A century of research has laid the foundations that give us a deep understanding of matter on the atomic scale, while at the same time, fabrication technologies have made it possible to manipulate matter and build devices on the nanometer scales where these quantum effects begin to manifest.
Uniting Academia and Industry Read about professors Lindsay LeBlanc and John Davis who are taking part in an initiative to push Alberta's progress in the quantum nanotechnology sphere. Al Meldrum Al Meldrum's areas of expertise include: condensed matter, nanotechnology, optical sensors, microcavities, quantum dots, fluorescence microscopy and spectroscopy, and photonic microfluidics. Our research straddles three main disciplines: material science, quantum optics and information security. Through the hybridisation of these fields, we are driving a unique research activity; investigating the application of light-matter interfaces in low-dimensional structures for physical security applications.
We have recently demonstrated the room-temperature operation of non-volatile, low-voltage, compound-semiconductor memory cells with a non-destructive read that has the potential to fulfil all the requirements of universal memory patent pending. A project is currently available that will form part of this unique and exciting on-going research programme, with a particular focus on shrinking memory cells to the nanoscale. The project will develop advanced III-V nanowires on silicon and 2D materials by molecular beam epitaxy and explore the device applications in next-generation photodetectors, fully-functional silicon photonic circuits, ultra-fast nanoelectronics and spitronics.
The project aims to develop high quality positioned quantum dot via droplet epitaxy and to explore the application in quantum optics.
This is a joint proposal from two 50th Anniversary lecturers in Physics and the Materials Science Institute to establish a completely new paradigm for the bottom-up growth of complex nanostructured layers targeting the ultimate level of miniaturisation in data storage and processing. The supervisors BR and SJ have an extremely strong track record in producing high impact publications, both as first authors and collaboratively. We expect the student working on this project will publish multiple publications in leading journals, with at least one as the first author, and commensurate conference presentations.
For most high-tech applications we make things better by making them smaller. This PhD project is truly interdisciplinary sitting at the interface of synthetic chemistry, quantum physics and device engineering, with a significant cross-over into areas traditionally in the field of data science.
What's So Special about the Nanoscale? | Nano
The project aims to explore new methods for the scalable fabrication of ultrathin organic films with tailored quantum interference properties and tuneable electrode interactions. Traditionally, organic layers are formed from solution-phase deposition via techniques such as molecular self-assembly or Langmuir-Blodgett deposition. Here you will use newly established UHV capabilities in Physics to explore sublimation deposition, the direct transition from a solid to gas phase without passing through the intermediate liquid phase, of a range of tailored organic materials.
Broadly the PhD project will:. The project targets the explanation of recently discovered extreme thermoelectric phenomena in nanostructures 2D Van der Waals materials such as graphene, and transition metal dichalcogenides and their heterostructures. A state-of-the-art experimental suite is available at Physics Department in collaboration with the National Graphene Institute to explore novel physical phenomena in these advanced materials.
These devices are of interest because they could be used in instrumentation for environmental gas monitoring, medical imaging, free-space optical communications and other applications. However, the quantum efficiency of mid-infrared LEDs is significantly lower than those operating in the visible or near-infrared. Resonant cavity designs and flip-chip geometry can be used to increase optical extraction.
Meanwhile, quantum dot structures have shown promising results and room temperature electroluminescence from LEDs containing InSb quantum dots has been obtained. In this project, we aim to fabricate and characterize novel Mid-infrared LEDs based on 5-component digital alloy nanostructures grown by molecular beam epitaxy MBE. The pentanary materials offer useful advantages to the device engineer because the presence of the fifth element in the alloy allows an additional degree of freedom for tailoring the performance of the device.
For example, by fixing the bandgap and the lattice constant, the alloy composition can be varied to independently adjust material properties, such as the refractive index or the spin-orbit split-off bandgap, for suppressing nonradiative Auger recombination and intervalence band absorption, which should ultimately improve device performance. Pentanary alloys can also be used with great effect as barriers and recently, strained type I quantum well LEDs and lasers containing pentanary AlInGaAsSb barriers have been demonstrated.
The discovery of graphene led to an explosion of interest in two dimensional 2D materials. In recent years many other atomically-thin materials have been isolated and studied, with a wide range of different properties. Direct-gap semiconductors could revolutionise the optoelectronics industry, reducing the size, weight and power requirements of conventional devices such as displays, emitters, modulators and detectors, and also opening a new field in which the quantum properties of light are harnessed. Atom-scale defects in 2D materials have been shown to efficiently emit quantum light, which is a sought-after resource for many applications in quantum information processing.
Guiding the light emitted by these centres in useful directions, to make use of it, is an outstanding challenge that this project aims to address. You will be taught how to create the required structures using nanofabrication tools in the cleanroom, and the quantum nature of the light emitted will be assessed using a quantum electro-optics laboratory housed in Isolab.
Choi, R. Young et al. New Journal of Physics 13, — see also goo. Noori et al. ACS Photonics 3, Superconducting quantum circuits are commonly regarded as artificial atoms as they have discrete energy levels between which transitions are possible. High tunability of energy levels makes these structures promising for applications in quantum computing and quantum sensing. The large dipole moment of the artificial atoms makes it easy to couple them to electromagnetic modes of resonators in the microwave range. Currently, this coupling is widely used for interqubit interaction, lasing, etc.
In this project, we propose to study quantum systems in which superconducting artificial atoms will be coupled to surface acoustic wave SAW resonators. This is a novel area of experimental condensed matter physics, where Lancaster University can play a significant role. The speed of the surface acoustic waves is five orders of magnitude smaller than the speed of light, thus the devices based on SAW can find application as a memory element in quantum computing.
What is more interesting, we are going to realise the strong coupling regime in which artificial atoms will emit spontaneously into the SAW resonator, i. The student will learn the best from quantum physics, ultralow temperature cryogenics, microwave engineering and nanofabrication. This combination will provide the student with a set of highly desirable transferable skills.
We are going to submit a grant application within the QuantERA call the deadline is 18 February The unit of electric current, the ampere, one of the seven SI base units, has undergone a major revision recently. The previous definition, which was difficult to realise with high precision in practice, was replaced by a definition that is more intuitive and easier to implement. From May , the ampere will be defined in terms of the fundamental constant, the elementary charge e , which was fixed for this purpose. This calls for the development of ultra-stable DC sources based on the highly controlled transfer of individual electrons that can be prototypes of the future DC standard.

Coulomb blockade devices offer the possibility of controlling charge transport in electrical circuits at the level of elementary charge and have the potential to produce DC with unprecedented accuracy. One of such promising devices is the so-called a SINIS single-electron transistor containing ultrasmall tunnel junctions made of superconductors and normal metals. In this project, you will design, fabricate and measure the SINIS single-electron transistor to understand and eliminate error events in electron tunnelling.
We apologize for the inconvenience...
The project will be conducted in collaboration with Aalto University and the National Physical Laboratory. The fabrication will take place in the cleanroom of the Lancaster Quantum Technology Centre. The fabricated devices will be characterised in a dilution refrigerator at millikelvin temperatures.
