Senior Research Fellow – Theory of GeSn Quantum Devices

GF-13 Senior Research Fellow – Theory of GeSn Quantum Devices

Contract: Part Time/Fixed Term

Applications are invited for a Senior Research Fellow position in the Quantum Electronic Devices group to work on a project to investigate GeSn alloys and their consequences for quantum information devices. Considerable progress has been made in recent years in the development of GeSn alloys for their use in high-mobility field-effect transistors and direct-gap photonic devices. This position aims to investigate theoretically the potential to use GeSn as a materials platform for quantum devices for spin qubit realisation in electrostatically defined quantum dots and quantum sensing.

The topic is part of an SFI-funded project aiming at the demonstration of the first operational GeSn quantum devices, capitalising on unique material band structure properties, and so place GeSn on the roadmap for future quantum computing and information processing technologies. The project is a collaboration between Tyndall and the Centre of Advanced Photonics and Process Analysis (CAPPA) of Munster Technological University. Gate-defined quantum dots will be fabricated at Tyndall’s cleanrooms to realise qubits and quantum sensors. The primary responsibility of the Fellow will be to drive an ambitious research programme that aims at the modelling of the quantum devices and the simulation of the quantum dynamics including all key materials and device design parameters. Close collaboration with the experimentalists is expected to guide the design of the fabricated devices and the interpretation of the measurements. Overall, the aim is to address how these novel materials can be best controlled and optimised to drive the development of a range of strategically important quantum devices.

The Fellow will be embedded in the Quantum Electronic Devices group within the CMOS++ Research Cluster of the Micro & Nano Systems Centre (MNS) at Tyndall. CMOS++ brings together over 15 research leaders across Tyndall to address emerging materials, devices and architectures for next generation information-processing technologies that interface with and advance beyond CMOS.

Key Responsibilities

  • Development / linkage of continuum simulation tools, which include Spin and Coulomb blockade in quantum dot arrays and the electronic structure description of strained GeSn alloys (both low- and high- Sn content), for technology design for application to technologically relevant problems
