Optical detectors are a very crucible part of many house appliances that are inseparable from our daily life. Photodetectors are very useful devices for light detection, imaging science, spectroscopies as well as for optical communication. Due to rapidly growing optical fiber based communication network, the development of high efficient and high speed photodetectors operating in the infra-red (IR) range are in huge demand. IR photodetectors are utilized for remote temperature sensing, night vision cameras, and astronomy. Recently developed layered transition metal chalcogenides (TMCs) have been proven as the possible solution for the development of high performance and flexible optical detectors. TMCs show an appropriate and tunable band gap with a high carrier mobility (0.2 eV to 2 eV), which makes TMCs a favourite material for high-efficiency optoelectronic devices.
In recent years, we have analysed the photodetection properties of various types of TMCs such as TiS3, TiS2, MoS2, etc. [1-4]. We also analysed the various types of heterostructures based on TMCs such as Ag-TiS3, Ag-TiS2, TiS3-porous silicon and TiS2-porous silicon. Photodetection properties of flexible nanocomposite materials based on ceramic-gel-TMCs have also been analysed. We also developed flexible photodetectors on the PET substrate. Various types of sample fabrication processes such as dielectrophoresis, drop-cast, gel-cast, etc. have been employed in order to develop high-performance photodetectors. The various effects of operating temperature have been investigated for the photodetector performance. Finally, ultra-sensitive, high-performance broadband photodetectors have been developed for a wide operating temperature range (77 K - 548 K).
