摘要: Janus 过渡金属硫族化合物范德华异质结中的偶极矩调控是当下凝聚态物理领域的前沿研究方向.本文从原子尺度构建了Janus MoSSe/MoS2范德华异质结中带隙与外电场和偶极矩相关的理论模型,并阐明了其潜在的物理机制.这不仅深化了对电场-偶极矩协同效应这一基础物理问题的理解,同时为相关教学提供了典型案例,有助于提升学生对电偶极子模型的理论认知及其在多学科领域应用中的理解深度.

Abstract: The manipulation of dipole moments in Janus transition metal dichalcogenide van der Waals heterojunctions is a cutting-edge research topic in condensed matter physics. This study develops an atomic-scale theoretical model to investigate the bandgap modulation in Janus MoSSe/MoS2 heterojunctions under external electric fields and dipole moments, revealing the underlying physical mechanisms. Our work not only advances the fundamental understanding of the interplay between electric fields and dipoles, but also serves as an instructive case study, enhancing students theoretical and applied knowledge of dipole models in multidisciplinary contexts.

Key words: two-dimensional semiconductor, dipole moment, external electric field, band alignment
