Interlayer Exciton Optoelectronics in a 2D Heterostructure p-n Junction
Jason S. Ross, Pasqual Rivera, John Schaibley +9
Semiconductor heterostructures are backbones for solid state based optoelectronic devices. Recent advances in assembly techniques for van der Waals heterostructures has enabled the…
Directional Interlayer Spin-Valley Transfer in Two-Dimensional Heterostructures
John R. Schaibley, Pasqual Rivera, Hongyi Yu +7
Van der Waals heterostructures formed by two different monolayer semiconductors have emerged as a promising platform for new optoelectronic and spin/valleytronic applications. In a…
Many-body effects in nonlinear optical responses of 2D layered semiconductors
Grant Aivazian, Hongyi Yu, Sanfeng Wu +5
We performed ultrafast degenerate pump-probe spectroscopy on monolayer WSe2 near its exciton resonance. The observed differential reflectance signals exhibit signatures of strong m…
Interlayer coupling in commensurate and incommensurate bilayer structures of transition metal dichalcogenides
Yong Wang, Zhan Wang, Wang Yao +2
The interlayer couplings in commensurate and incommensurate bilayer structures of transition metal dichalcogenides are investigated with perturbative treatment. The interlayer coup…
Magnetisms in -type monolayer gallium chalcogenides (GaSe, GaS)
Sianxin Wu, Xia Dai, Hongyi Yu +3
Magnetisms in -type monolayer GaX (X=S,Se) is investigated by performing density-functional calculations. Due to the large density of states near the valence band edge, these mo…
Nonlinear valley and spin currents from Fermi pocket anisotropy in 2D crystals
Hongyi Yu, Yue Wu, Gui-Bin Liu +2
Controlled flow of spin and valley pseudospin is key to future electronics exploiting these internal degrees of freedom of carriers. Here we discover a universal possibility for ge…
