Landau level gaps in high mobility black phosphorus devices

ORAL

Abstract

Black phosphorus (BP) has recently attracted wide interest as a high mobility two-dimensional semiconductor. Here we report encapsulated few-layer BP field effect transistors achieving high field effect mobility at cryogenic temperatures and observation of the integer quantum Hall effect in high magnetic field. We examine the devices' anisotropic transport properties and the Landau level gaps by varying temperature and magnetic field. Latest results will be discussed and compared with theoretical models.
