PhD in Engineering - Ultrafast Semiconductors for Quantum Nano-electronics

   College of Science and Engineering

  ,  Monday, May 15, 2023  Competition Funded PhD Project (UK Students Only)

About the Project

Several prominent quantum technologies rely on high quality semiconductors to create, manipulate and detect quantum information, also known as ‘qubits’.

Semiconductor quantum nanoelectronics have a large scalability potential, which means that several qubits can be integrated on a single device using well established nanofabrication techniques.

One of the greatest challenges in this field is to convey the quantum information from a quantum device to the outside (classical) world. In this PhD project we will use 2-dimensional semiconductor materials (i.e. InGaAs/InAlAs, GaAs/AlGaAs, graphene) and create advanced quantum devices with the aim of improving the connectivity between quantum and classical worlds. We will expore the transport properties of this materials using DC signals as well as high frequency Terahertz (THz) signals and identify the advantages and limitations of the nanofabrication techniques.  

The PhD candidate will work with high quality 2D semiconductors, such as GaAs, InGaAs and graphene. In addition, the candidate will explore aspects of high frequency electronics (THz), both from the theoretical and experimental point of view. The PhD candidate will be also be involved in advanced nanofabrication in our state-of-the-art James Watt Nanofabrication Centre (JWNC), perform electromagnetic simulations of the devices and experimentally measure the novel semiconductors at both room temperature and cryogenic temperatures.

By the end of the project, the student will develop skills in nanofabrication of quantum devices, high frequency spectroscopy techniques (THz), cryogenic instrumentation, simulation and modelling as well as electronic measurements of nano-electronic devices.

The project will require both individual and group work in collaborative environments and the successful candidate should be capable of working in both environments. Experience with computer programming (C or C++ or Python or Matlab etc) or data acquisition and analysis is not essential but it is advantageous.

  • We are looking for motivated and enthusiastic candidates with interests in Quantum Technology or Nanoscience or High Frequency Nanoelectronics.
  • You will need to have an MSc degree (or equivalent) in Physics or Engineering or Nanosciences.
