Theoretical study of structural, electronic and optical properties of bismuth-selenide, bismuth-telluride and antimony-telluride/graphene heterostructure for broadband photodetector

It remains challenging to produce high-performance broadband photodetector that can detect light from infrared to ultraviolet frequency range for biomedical imaging, gas sensing and optical communication applications. In particular, large energy band gap and low optical absorption in the material ut...
