Abstract

In this work, we demonstrate a Sb₂Te₃/MoS₂ heterostructure photodetector for visible range detection or sensing applications with ultra-low dark current and high sensitivity at zero external bias. The photoresponsivity can reach to 156 mA/W at zero bias and can be enhanced 3 times at 1V bias voltage.
