Stacking up electron-rich and electron-deficient monolayers to achieve extraordinary mid- to far-infrared excitonic absorption: Interlayer excitons in the C3B/C3N bilayer
Zhao Tang, Greis J. Cruz, Fanhao Jia +3
Our ability to efficiently detect and generate far-infrared (i.e., terahertz) radiation is vital in areas spanning from biomedical imaging to interstellar spectroscopy. Despite dec…
Giant excitonic effects in bulk vacancy-ordered double perovskites
Fan Zhang, Weiwei Gao, Greis J. Cruz +3
Using first-principles GW plus Bethe-Salpeter equation calculations, we identify anomalously strong excitonic effects in several vacancy-ordered double perovskites Cs2MX6 (M = Ti,…
Prediction of protected band edge states and dielectric tunable quasiparticle and excitonic properties of monolayer MoSiN
Yabei Wu, Zhao Tang, Weiyi Xia +6
The electronic structure of two-dimensional (2D) materials are inherently prone to environmental perturbations, which may pose significant challenges to their applications in elect…
Combined sub-sampling and analytical integration for efficient large-scale calculations for 2D systems
Weiyi Xia, Weiwei Gao, Gabriel Lopez-Candales +4
Accurate and efficient predictions of the quasiparticle properties of complex materials remain a major challenge due to the convergence issue and the unfavorable scaling of the com…
Remarkable band gap renormalization via dimensionality of the layered material C3B
Yabei Wu, Weiyi Xia, Yubo Zhang +3
Layer-dependent electronic and structural properties of emerging graphitic carbon boron compound C3B are investigated using both density functional theory and the GW approximation.…
Thermoelectric probe of defect state induced by ionic liquid gating in vanadium dioxide
Hui Xing, Peihong Zhang, Hao Zeng
Thermoelectric measurements detect the asymmetry between the density of states above and below the chemical potential in a material. It provides insights into small variations in t…
