Tellurium@Selenium nanotube heterojunctions as promising material for photodetectors

25 апреля, 2019 - 12:55
Researchers demonstrate, for the first time, a tellurium@selenium (Te@Se) heterostructure used as a working material in a photoelectrochemical-type photodetector. Specifically, Te@Se nanotube heterojunctions synthesized by epitaxial growth of selenium on tellurium nanotubes exhibit a largely enhanced self-powered photoresponse, significantly improved photocurrent density, and photoresponsivity compared to those of Te or Se nanomaterials.
