IIT Delhi, BTPL Collaborates to Develop First in India Diamond Based UV Photodetectors

New Delhi, 16th October, 2024: The Indian Institute of Technology (IIT Delhi) has collaborated with M/s Bhathwari Technologies Pvt. Ltd. (BTPL), Surat for the development of diamond-based deep ultraviolet (UV) photodetectors for the first time in India. IIT Delhi has signed the collaboration with BTPL, who synthesise diamonds using the Chemical Vapour Deposition (CVD) technique. The deep UV photodetectors uncover the practice in the areas of UV imaging, biological detection, secure communication, and military detection, to name a few.

These photodetectors provide highly selective photo response in the deep UV region and high efficiency at room temperature (RT). During the process, BTPL will provide high-quality CVD-grown diamond samples to IIT Delhi and then IIT Delhi will design and develop UV photodetectors under research led by Prof. Rajendra Singh from the Department of Physics.

Bakul bhai Limbasiya, Chairman of BTPL expressed his happiness through this collaboration stating, “We had synthesized 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.” He added, “This collaboration is a joint Academia-Industry collaboration for the indigenous development of Diamond 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.”

Prof. Rajendra Singh from the Department of Physics at IIT Delhi shared his delight saying, “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.”
