Momentum-Resolved Relaxation-Time Approach for Size-Dependent Conductivity in Anisotropic Metallic Films
YoungJun Lee, Jin Soo Lee, Seungjun Lee +2
Shrinking CMOS interconnect dimensions to the nanometer scale intensifies electron scattering at surfaces, interfaces, and grain boundaries, causing severe conductivity loss and ch…
Anisotropic Strain Relaxation-Induced Directional Ultrafast Carrier Dynamics in RuO2 Films
S. G. Jeong, I. H. Choi, S. Lee +9
Ultrafast light-matter interactions inspire potential functionalities in picosecond optoelectronic applications. However, achieving directional carrier dynamics in metals remains c…
Giant piezoelectricity in group IV monochalcogenides with ferroelectric AA layer stacking
Seungjun Lee, Hyeong-Ryul Kim, Wei Jiang +2
The piezoelectricity of group IV monochalcogenides (MXs, with M = Ge, Sn and X = S, Se) has attracted much attention due to their substantially higher piezoelectric coefficients co…
Establishing Epitaxial Connectedness in Multi-Stacking: The Survival of Thru-Holes in Thru-Hole Epitaxy
Youngjun Lee, Seungjun Lee, Jaewu Choi +2
Thru-hole epitaxy has recently been reported to be able to grow readily detachable domains crystallographically aligned with the underlying substrate over 2D mask material transfer…
Charge-to-spin conversion in twisted graphene/WSe heterostructures
Seungjun Lee, D. J. P. de Sousa, Young-Kyun Kwon +4
We investigate the twist angle dependence of spin-orbit coupling (SOC) proximity effects and charge-to-spin conversion (CSC) in graphene/WSe heterostructures from first princip…
Thru-Hole Epitaxy: Is Remote Epitaxy Really Remote?
Dongsoo Jang, Chulwoo Ahn, Youngjun Lee +6
The remote epitaxy was originally proposed to grow a film, which is not in contact but crystallographically aligned with a substrate and easily detachable due to a van der Waals ma…
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…
