Simple linear response model for predicting energy band alignment of two-dimensional vertical heterostructure
Javad G. Azadani, Seungjun Lee, Hyeong-Ryul Kim +4
The Anderson and midgap models are often used in the study of semiconductor heterojunctions, but for van der Waals (vdW) vertical heterostructures they have shown only very limited…
Versatile Physical Properties of a Novel Two-Dimensional Materials Composed of Group IV-V Elements
Seungjun Lee, Young-Kyun Kwon
Owing to the fascinating physical characteristics of two-dimensional (2D) materials and their heterostructure, much effort has been devoted to exploring their basic physical proper…
Unveiling Giant Hidden Rashba Effects in Two-Dimensional SiBi
Seungjun Lee, Young-Kyun Kwon
Recently, it has been known that the hidden Rashba (R-2) effect in two-dimensional materials gives rise to a novel physical phenomenon called spin-layer locking (SLL). However, not…
Low Lattice Thermal Conductivity of a Two-Dimensional Phosphorene Oxide
Seungjun Lee, Seoung-Hun Kang, Young-Kyun Kwon
A fundamental understanding of the phonon transport mechanism is important for optimizing the efficiency of thermoelectric devices. In this study, we investigate the thermal transp…
