Intrinsic mobility due to electron-phonon interaction in black phosphorus. — •Sergey Brener, Alexander Rudenko, and Mikhail Katsnelson — Radboud Universiteit, Niederlanden

Flexural and in-plane thermal fluctuations in crystalline membranes affect the band structure of the carriers, which has an effect on transport properties of 2D systems. I consider a specific example of one-layer black phosphorus, which is a highly anisotropic material, and present our recent results on intrinsic carrier mobility. In contrast to graphene, where the mobility is determined by two-phonon (flexural) scattering, in black phosphorus one-phonon (in-plane) processes dominate.
