摘要

摘要 在交叉电场和磁场中,推导出了单层过渡金属二卤化物中电子的光谱和波函数的精确解析表达式。计算了带间转变强度的电场依赖性。带间吸收的谷选择性在很大程度上取决于电场,并且在电场增加时,谷选择性的符号会成倍反转。

Light Absorption in Dichalcogenides of Transition Metals in Crossed Fields

Abstract

Exact analytic expressions are derived for the spectrum and wavefunctions of electrons in a monolayer of transition metal dichalcogenides in crossed electric and magnetic fields. The electric field dependence of interband transition intensity is calculated. The valley selectivity of interband absorption considerably depends on the electric field and can reverse its sign multiply upon an increase in this field.
