Electronic Structure and Optical Properties of Twisted Bilayer Black Phosphorus

ORAL

Abstract

Using first-principles calculations, we find that the electronic structure and optical properties of bilayer black phosphorus can be modified significantly through changing the interlayer twist angle. We demonstrate the origin of these twist angle dependent effects, and connect our predicted results to experimental measurements.
