Robust Light Detection from Ultraviolet to Near‐Infrared with ZnGa2O4/p‐Si Heterojunction Photodiode and Its Application for Optoelectronic Physically Unclonable Functions

Robust Light Detection from Ultraviolet to Near‐Infrared with ZnGa2O4/p‐Si Heterojunction Photodiode and Its Application for Optoelectronic Physically Unclonable Functions

Abstract The Si‐based self‐powered broadband photodiode (SSBP) is prized for its ability to swiftly detect light across a wide spectrum without requiring an external voltage. However, boosting its efficiency remains challenging due to its high refractive index and limited UV light penetration. A com...
