Anisotropic Quantum Transport in Black Phosphorus Two-dimensional Hole Gas

ORAL

Abstract

High-mobility two-dimensional (2D) electron system in black phosphorus van der Waals heterostructures has provided a new platform for studying electron-electron interaction in 2D. In particular, the large anisotropy distinguishes black phosphorus from other high-mobility two-dimensional (2D) electron systems. Here, we observed that new anisotropic states emerge at fractional filling factors for spin-split Landau levels N > 4. The new states manifest as resistance maxima or minima when current flows in different directions. Our results indicate the formation of charge-density-wave stripe phase in black phosphorus 2D hole gas that is surprisingly robust against thermal fluctuation and impurity scattering.
