- Diamond being the third-generation wide band gap semiconductor, will be used as deep UV photodetector having improved deep UV photo response
M/s Bhathwari Technologies (BTPL), Surat, a company in the area of synthesis of diamonds using Chemical Vapour Deposition (CVD) technique, has signed an MoU with IIT Delhi for the development of diamond-based deep ultraviolet (UV) photodetectors.
The deep UV photodetectors find applications in the area of UV imaging, secure communication, biological detection, military detection, etc. The advantages of these photodetectors are their highly selective photo response in the deep UV region and high efficiency at room temperature (RT) and even at higher temperatures.
Under this collaborative work, BTPL will provide CVD grown diamond samples to IIT Delhi. The design and development of the UV photodetectors will be carried out by IIT Delhi researchers led by Prof Rajendra Singh from the Department of Physics.
Singh’s research group in India has a long-standing experience in developing UV and Deep UV photodetector technology based on wide bandgap semiconductor materials such as Gallium nitride (GaN), Aluminum gallium nitride (AlGaN), Alumimun nitride (AlN) and Gallium oxide (Ga2O3).
Diamond being the third-generation wide band gap semiconductor, will be used as deep UV photodetector having improved deep UV photo response and improved efficiency suitable for defence and space applications.
