Title : Fabrication of detectors based on semiconductor heterostructures for optical communication
Abstract:
Heterostructure based devices has shown great potential in optoelectronic field especially in optical communication. Heterostructure optoelectronic devices have been fabricated with unique morphology which exhibit higher photocurrent generation and significantly enhanced responsiveness towards UV illumination. The fabricated device display substantial low dark current and fast time-correlated transient response and very high photo responsivity in self-powered mode of operation. Further, chemically synthesized novel quantum dots have been utilized as sensitizer alongwith various metal selenides for the fabrication heterostructure. The fabricated device exhibits broadband optical response with state-of-the art performance parameters. I’ll discuss these findings in details with possible mechanism.
