Twist driven deep-ultraviolet-wavelength exciton funnel effect in bilayer boron nitride
Linghan Zhu, Yizhou Wang, Li Yang
Realizing direct-bandgap quantum dots working within the deep-ultraviolet frequency is highly desired for electro-optical and biomedical applications while remaining challenging. I…
Point Defects in Two-Dimensional RuCl3
Wenqi Yang, Linghan Zhu, Yan Lu +2
Defects are crucial in determining a variety of material properties especially in low dimensions. In this work, we study point defects in monolayer alpha-phase Ruthenium (III) chlo…
Multi-Meron Interactions and Statistics in Two-Dimensional Materials
Xiaobo Lu, Linghan Zhu, Li Yang
As a fundamental type of topological spin textures in two-dimensional (2D) magnets, a magnetic meron carries half-integer topological charge and forms a pair with its antithesis to…
Electric field tuning of magnetic states in single magnetic molecules
Yan Lu, Yunlong Wang, Linghan Zhu +2
Single magnetic molecules may be the smallest functional magnets. An electric-field controllable spin state of magnetic molecules is of fundamental importance for applications whil…
Manipulating Interlayer Excitons for Ultra-pure Near-infrared Quantum Light Generation

Interlayer excitons (IXs) formed at the interface of atomically-thin semiconductors possess various novel properties. In a parallel development, nanoscale strain engineering has em…
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…
Flat-Bands-Enabled Triplet Excitonic Insulator in a Di-atomic Kagome Lattice
Gurjyot Sethi, Yinong Zhou, Linghan Zhu +2
The excitonic insulator (EI) state is a strongly correlated many-body ground state, arising from an instability in the band structure towards exciton formation. We show that the fl…
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…
Quasiparticle Energies and Excitonic Effects of Chromium Trichloride: from Two Dimensions to Bulk
