Theoretical investigation of the vertical dielectric screening dependence on defects for few-layered van der Waals materials
Amit Singh, Seunghan Lee, Hyeonhu Bae +3
First-principle calculations were employed to analyze the effects induced by vacancies of molybdenum (Mo) and sulfur (S) on the dielectric properties of few-layered MoS2. We explor…
Electrostatic moiré potential from twisted-hBN layers
Dong Seob Kim, Roy C. Dominguez, Rigo Mayorga-Luna +17
Moiré superlattices formed by vertically stacking van der Waals layers host a rich variety of correlated electronic phases and function as novel photonic materials. The moiré poten…
PT-symmetry enabled spin circular photogalvanic effect in antiferromagnetic insulators
Ruixiang Fei, Wenshen Song, Lauren Pusey-Nazzaro +1
The short timescale spin dynamics in antiferromagnets is an attractive feature from the standpoint of ultrafast spintronics. Yet generating highly polarized spin currents at room t…
Switchable enhanced spin photocurrent in Rashba and cubic Dresselhaus ferroelectric semiconductors
Ruixiang Fei, Shuaiqin Yu, Yan Lu +2
Generating and controlling spin current (SC) are of central interest in spin physics and applications. To date, the spin-orbit interaction (SOI) is an established pathway to genera…
Nonreciprocal Second-Harmonic Generation in Few-Layer Chromium Triiodide
Wenshen Song, Ruixiang Fei, Li Yang
It is of fundamental importance but challenging to simultaneously identify atomic and magnetic configurations of two-dimensional van der Waals materials. In this work, we show that…
Giant linearly-polarized photogalvanic effect and second harmonic generation in two-dimensional axion insulators
Ruixiang Fei, Wenshen Song, Li Yang
The second-order nonlinear optical (NLO) processes, such as the photogalvanic effect and second-order harmonic generation (SHG), play crucial roles in probing and controlling light…
