Abstract:Herein, an infrared (IR) photodetector has been demonstrated by depositing the (V0.99Cr0.01)2O3 films on top of a sapphire (Al2O3) wafer. The photoresponse properties, including photocurrent, voltage, responsivity, and response speed, at different temperatures and wavelengths are explored. The results showed that the deposited samples produce a significant photoresponse in the near‐IR (NIR) light. In particular, as temperature increases from 298 K (25 °C) to 453 K (180 °C), the responsivity of (V0.99Cr0.01)2O3… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
