EPSRC ICASE Studentship at The University of Sheffield with Selex ES

University of Sheffield

This ICASE studentship is a partnership between the Advanced Detection Centre at The University of Sheffield and Selex EX, Southampton.

Project title: Development of high sensitivity very long wave infrared photo detectors 

Project overview:
The Advanced Detection Centre has a wide range of expertise ranging from design, modelling, fabrication and characterisation of detectors. We offer expertise in development of detection systems from X-ray to Infrared, single photon detection, high speed applications, to quantitative temperature measurements.

In this project, we aim to develop novel infrared detectors. Infrared wavelengths above 10 mm, termed very long infrared (VLWIR) are exploited in a wide range of applications ranging from measuring temperature and water vapour concentration at different atmospheric heights, characterisation of chemicals and gasses, to quality control in manufacturing. Despite the importance, a high speed, high sensitivity and large format VLWIR array is still missing in current detector technology portfolio. Type II superlattice (T2SL) photo detectors will be developed to fill this technology gap. Using strain engineering the Auger recombination will be suppress to achieve low dark current.

You will work closely with crystal growers to develop high quality T2SL semiconductor wafers, and develop fabrication process to demonstrate high performance T2SL detectors. You will also develop the technology in close consultation with Selex who will steer the device specifications. Placement at Selex will provide an excellent training opportunity and enhance your understanding of the applications of T2SL detectors. 

Applicants should hold a minimum of a UK Honours Degree at 2:1 level in Electronic Engineering or Physics. Candidates with other relevant backgrounds such as Materials Engineering may also be considered.

Applicants must have UK Home Fee status, or EU citizenship and been resident in the UK for at least three years prior to the start of the project. Excellent organisational and communication skills are required, along with a keen interest to engage in industry focussed research.

Funding details:
The project is funded for a total of 4 years, which includes a placement opportunity at Selex ES, Southampton. The studentship includes full payment of fees and a tax-free stipend of £18,000-20,000 pa. The PhD may be started at any time up to 1st October 2016.
