Ata Khalid was appointed as Lecturer in Sensors and Sensor Systems at Cranfield Defence and Security, Defence Academy of UK, Cranfield University, Shrivenham in 2017. Ata has strong links with Glasgow and he is a visiting researcher at Glasgow University. Ata is an expert in compound semiconductor devices and Nano fabrication technologies. His interest are mid-IR sources and detectors based on InSb semiconductor material. He has also demonstrated a long track record in solid-state THz device science and engineering. He has published more than 170 articles in the compound semiconductor, microwave/THz and photonics domains, a full list can be found here ( ). He was a co-investigator (Co-I) in the EPSRC project EP/H011862/1 on planar Gunn diode technology, and is currently a Co-I in the €4 million TeraApps Horizon 2020 project (765426, 2018-2021) Marie Curie Innovative Training Network on THz electronics and photonics. He led the development of the planar Gunn diode as a solid-state THz source as well as related enabling technologies for imaging applications. He has also published on the design, integration and fabrication of mid-infrared (IR) photo-pixel for two-dimensional imaging arrays and on terahertz resonant tunnelling diode (RTD) sources. Ata’s research highlights include the breakthrough demonstration of the first planar InGaAs Gunn diode operation above 100 GHz and then above 300 GHz. A technique he developed for THz signal detection was taken up by the multinational company Keysight Technologies, and is now embedded in their commercial products.
