Single-photon counting - the ability to faithfully capture the single quantum of light - is a critical capability for a wide range of new low-light sensing applications and a host of emerging photonic quantum technologies.
We have been awarded funding for a multi-partner project to develop high-sensitivity optical detector for single-photon counting. The project aims to significantly expand the operational region of single-photon detectors well beyond the current limits, expanding into short- and mid-wave infrared regions. We will produce revolutionary new cameras with picosecond timing resolution which can be used, for example, to see though fog in automotive lidar scenarios, as well as allowing imaging and sensing in new applications in environmental monitoring, healthcare, and security and defence.
We are seeking a motivated PhD student to join the team of academics and post-doctoral researcher at Sheffield for this project. Working as part of the team, the typical tasks for the PhD student include wafer design of III-V semiconductor optical detector (using in-house and commercial device simulation programs); device fabrication; measurements of key performance characteristics for the fabricated optical detector; collaborating with other researchers on the same project at other partner organisations as well as other researchers in the Sheffield research group.
• Full funding for UK and resident EU candidate (> 3 years) • Substantial partial funding for international students.
1. A 1st or 2:1 class honours undergraduate degree OR MSc degree (with Distinction/Merit) in Electronic Engineering or Physics. 2. Experience or strong interest in semiconductor-related simulation/device fabrication/measurements.
The PhD student will be supervised by Prof Chee Hing Tan, Department of Electronic & Electrical Engineering, The University of Sheffield.
