The Compound Semiconductor Applications (CSA) Catapult in Newport, Wales, UK is conducting a Roadmapping Exercise on Type II Superlattices (T2SLs) and related strained quantum layers. The Roadmapping Exercise will be conducted over a 6-month period starting in January 2022 and will end in a Final Report in October 2022. A Roadmapping Workshop will be held during the Institute of Physics (IOP) Photon2022 Conference and Industry Technology Programme (ITP) scheduled for August 30th – 2nd September 2022 at the Nottingham East Midlands Conference Centre. At that Conference, participants will meet in person or via teleconferencing means to finalise the T2SL Roadmap. The T2SL Roadmap will be published subsequently by the CSA Catapult in conjunction with the IOP.
T2SLs and related quantum strained layers are an emerging compound semiconductor photonics technology covering the short-wavelength infrared (SWIR) to the long-wavelength IR (LWIR) spectral ranges. T2SL detector technologies are increasingly becoming competitive with the gold standard Mercury Cadmium Telluride (MCT or CMT) detectors. However, while MCTs are also compound semiconductors, regulatory constraints around the use of Mercury products and processes are causing a shift in the balance towards other types of environmentally friendly detector technologies. Furthermore, although the enabling technologies around MCT detectors are fairly well developed e.g., cooling and readout technologies, there are opportunities for emerging semiconductor detectors and complementary technologies to operate at higher temperatures or near room temperature in addition to novel readout architectures. Furthermore, smaller size and lower energy consumption devices will help towards achieving a net-zero global energy economy.
This roadmap covers all areas of application including Biomedical, Healthcare, Defence, Security, Search & Rescue, Fire, Space, Transportation, and Aerospace.
