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…
Photo-degradation Protection in 2D In-Plane Heterostructures Revealed by Hyperspectral Nanoimaging: the Role of Nano-Interface 2D Alloys
Alireza Fali, Tianyi Zhang, Jason Patrick Terry +8
Single-layer heterostructures exhibit striking quasiparticle properties and many-body interaction effects that hold promise for a range of applications. However, their properties c…
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…
First-Principles Studies of Second-Order Nonlinear Optical Properties of Organic-Inorganic Hybrid Halide Perovskites
Wenshen Song, Guang-Yu Guo, Su Huang +2
Organic-inorganic hybrid halide perovskites have ignited tremendous interests for photovoltaic applications. However, their nonlinear optical response has not been studied although…
Strain-controlled fundamental gap and structure of bulk black phosphorus
Jie Guan, Wenshen Song, Li Yang +1
We study theoretically the structural and electronic response of layered bulk black phosphorus to in-layer strain. Ab initio density functional theory (DFT) calculations reveal tha…
