英文摘要	The dynamics of electron transport in single-layer MoS2 is simulated by employing the single particle Monte Carlo method. Acoustic phonon scattering, optical phonon scattering and Frohlich scattering are taken into account. It is found that the electron mobility decreases from 806 cm(2)/V.s for a transverse electrical field of 10(3) V/m to 426/112 cm(2)/V.s for a transverse electrical field of 10(5)/10(7) V/m. Further detailed analysis on carrier dynamics reveals that the low field mobility is dominated by the acoustic phonon scattering while the role of optical phonon scattering is to relax the electron energy below the optical phonon energy by efficient energy relaxation through optical phonon emission. Only when the transverse electrical field is larger than 10(6) V/m, the mobility can be determined by the optical phonon scattering, leading to a strong mobility degradation.; Physics, Multidisciplinary; SCI(E); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; ARTICLE; zenglang@ime.pku.edu.cn; xyliu@ime.pku.edu.cn; 2; 31
