Magnetic and moiré Proximity Effects in WSe2/WSe2/CrI3 Trilayers
Junyi Liu, Xu Zhang, Gang Lu
Integrating magnetic order to moiré superlattices is of significant scientific and technological interest. Based on first-principles calculations, we study the interplay of magneti…
Shedding Light on Moire Excitons: A First-Principles Perspective
Hongli Guo, Xu Zhang, Gang Lu
Moire superlattices in van der Waals (vdW) heterostructures could trap strongly bonded and long lived interlayer excitons. Assumed to be localized, these moire excitons could form…
Radiative recombination of large polarons in halide perovskites
Mingliang Zhang, Xu Zhang, Hai-Qing Lin
In halide perovskites, electrons (holes) exist as electronic (hole) polarons, excitons, free and trapped electrons (holes). Six kinds of collisions could lead to annihilation of el…
Charge Transport in Hybrid Halide Perovskites
Mingliang Zhang, Xu Zhang, Ling-Yi Huang +2
Charge transport is crucial to the performance of hybrid halide perovskite solar cells. A theoretical model based on large polarons is proposed to elucidate charge transport proper…
Comment on "Linear Scaling of the Exciton Binding Energy versus the Band Gap of Two-Dimensional Materials"
Mingliang Zhang, Ling-Yi Huang, Xu Zhang +1
In a recent letter [J. -H. Choi et al. Phys. Rev. Lett. 115, 066403 (2015)], a universal linear relation between the binding energy Eb of exciton and the band gap Eg is found in di…
Quantum Electrodynamics is Crucial for Plasmonic Resonance of Metallic Nanostructures
Mingliang Zhang, Hongping Xiang, Xu Zhang +1
Plasmonic resonance of a metallic nanostructure results from coherent motion of its conduction electrons driven by incident light. At the resonance, the induced dipole in the nanos…
Quantum Mechanical Simulations of Nanoindentation of Al Thin Film
Qing Peng, Xu Zhang, Gang Lu
QCDFT is a multiscale modeling approach that can simulate multi-million atoms effectively via density functional theory (DFT). The method is based on the framework of quasicontinuu…
Structure, mechanical and thermodynamic stability of vacancy clusters in Cu
Qing Peng, Xu Zhang, Gang Lu
The atomic structure, mechanical and thermodynamic stability of vacancy clusters in Cu are studied by atomistic simulations. The most stable atomic configuration of small vacancy c…
