Band structure of molybdenum disulfide: from first principle to analytical band model

نویسندگان

چکیده

A simple band model such as the effective mass approximation (EMA) can be used to quickly obtain lower-energy region for structure of monolayer molybdenum disulfide. But EMA cannot give correct description in higher-energy region. To address this major issue, we propose an analytical calculation (ABC) study Important parameters ABC are obtained by fitting three-direction disulfide from first-principles (FP) method. The proposed fits well with FP result We also use calculate physical quantities carrier transport density states and group velocity. Our extended further utilized calculating key ballistic 2D semiconductor materials.
