Research Projects

The BRICS project, BIO-LIGHT, aims to develop high-output power emitters and sensitive detectors based on AlGaN nanoheterostructures for deep-ultraviolet DUV radiation for biological applications. The project, involving Russia, China, and India, will develop compact DUV light sources and photodetectors in a wavelength range of 230-280nm. The project aims to improve detection of DUV light sources for public health. The study focuses on the development of high-performance photodetectors using group-III nitrides for solid-state lighting and high-power electronics. The key prerequisites for this include the crystalline quality of Al, Ga N heterostructures and their effective doping. The researchers will exploit the atomically thin binary GaN quantum wells QWs with potentially improved deep-UV light emission and extraction efficiencies to develop high-quality monolayer multilayer GaN/AlN nano-heterostructures on silicon/sapphire substrates. The study will use techniques such as time-resolved photoluminescence spectroscopy, x-ray diffraction analysis, Raman spectroscopy, atomic force, and transmission electron microscopes to investigate the physical phenomena of ultra-thin 2D-heterostructures. The devices will be exposed to AlGaN-based high-performance DUV-LEDs and electron beam pumped UV emitters for 230-280 nm spectral range.
