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…
Dislocation core properties of β-tin: A first-principles study
M. A. Bhatia, M. Azarnoush, I. Adlakha +2
Dislocation core properties of tin (β-Sn) were investigated using the semi-discrete variational Peierls-Nabarro model (SVPN). The SVPN model, which connects the continuum elasticit…
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…
