IIT Delhi Collaborates with BTPL to Develop Diamond-Based Deep UV Photodetectors
The Indian Institute of Technology (IIT) Delhi has collaborated with Bhathwari Technologies Pvt Ltd. (BTPL) to Develop Diamond-Based Deep UV Photodetectors. Bhathwari Technologies Pvt Ltd. is a Surat-based company that deals with the synthesis of diamonds using the Chemical Vapour Deposition (CVD) Technique. This is the first step taken in India to develop diamond-based ultraviolet photodetectors.
Bakul bhai Limbasiya, Chairman, BTPL, said, “We had synthesised the first Lab Grown Diamond (LGD) in India in 2001 and since then are actively engaged in developing the CVD reactors and related technology for LGDs. This collaboration is a joint Academia-Industry collaboration for the indigenous development of Diamond-Based photodetectors for the first time in India and is in line with the call of ‘Make in India’ and ‘Atmanirbhar Bharat’ given by our Hon. Prime Minister Shri. Narendra Modi.”
Deep UV Photodetectors
These Deep ultraviolet (UV) Photodetectors, UV imaging, secure communication, biological detection, military detection, etc., highly selective photo response in the deep UV spectrum, and high efficiency at room temperature (RT) and elevated temperatures are some of its useful features.
“Diamond is an ultra-wide bandgap semiconductor and possesses many interesting properties that could be useful for its applications in electronic and optoelectronic devices. This collaboration will accelerate the research and development in the area of diamond as a material and for its device applications”, said Rajendra Singh.
Singh's research group in India has developed UV Photodetectors using wide bandgap semiconductors like Gallium nitride (GaN), Aluminum gallium nitride (AlGaN), Aluminium nitride (AlN) and Gallium oxide (Ga2O3).
