Quantum Behaviour in a Black Phosphorus Two-Dimensional Electron System
Feb 24, 2017 at 12PM
Synopsis
Two-dimensional electron gases (2DEG) have allowed rich physical phenomena to be probed at the quantum level in condensed-matter physics-archive. Atomically thin black phosphorus provides a maximum level of quantum confinement, while introducing remarkable new physics-archive to the 2DEG due to their distinctive electronic structures. Recently,the observation of quantum oscillations and quantum Hall effect in a black phosphorus 2DEG with a high mobility has been reported. In this talk, I will explore the experimental set up and results of a black phosphorus 2DEG and discuss current research going on in black phosphorus.
