Reduction of Fermi level pinning at Cu-BP interfaces by atomic passivation

Xiao Zhou, Cheng Chen, Pengfei Ou

Black phosphorus (BP) is a semiconducting material with a direct finite band gap in its monolayer, attracting intense attention for its application in field-effect transistors. However, strong Fermi level pinning (FLP) has been observed for contacts betwee ...
