Understanding the origin of bandgap problem in transition and post-transition metal oxides
Hengxin Tan, Haitao Liu, Yuanchang Li +2
Improving electronic structure calculations for practical and technologically-important materials has been a never-ending pursue. This is especially true for transition and post-tr…
Half Excitonic Insulator: A Single-Spin Bose-Einstein Condensate
Zeyu Jiang, Yuanchang Li, Wenhui Duan +1
First-principles calculations reveal an unusual electronic state (dubbed as half excitonic insulator) in monolayer 1T-MX2 (M = Co, Ni and X = Cl, Br). Its one spin channel has a ma…
Electronic Fingerprints of Cr and V Dopants in Topological Insulator Sb2Te3
Wenhan Zhang, Damien West, Seng Huat Lee +6
By combining scanning tunneling microscopy/spectroscopy and first-principles calculations, we systematically study the local electronic states of magnetic dopants V and Cr in the t…
Enhanced Light Emission from the Ridge of Two-dimensional InSe Flakes
Yang Li§, Tianmeng Wang§, Han Wang§ +10
InSe, a newly rediscovered two-dimensional (2D) semiconductor, possesses superior electrical and optical properties as a direct bandgap semiconductor with high mobility from bulk t…
Revealing the Biexciton and Trion-exciton Complexes in BN Encapsulated WSe2
Zhipeng Li, Tianmeng Wang, Zhengguang Lu +9
Strong Coulomb interactions in single-layer transition metal dichalcogenides (TMDs) result in the emergence of strongly bound excitons, trions and biexcitons. These excitonic compl…
Realizing intrinsic excitonic insulator by decoupling exciton binding energy from the minimum band gap
Zeyu Jiang, Yuanchang Li, Shengbai Zhang +1
Direct-gap materials hold promises for excitonic insulator. In contrast to indirect-gap materials, here the difficulty to distinguish from a Peierls charge density wave is circumve…
Long Range Magnetic order stabilized by acceptors
Xiaodong Zhang, Jingzhao Zhang, Shengbai Zhang +1
Tuning magnetic order in magnetic semiconductors is a long sought goal. A proper concentration of acceptors can dramatically suppress local magnetic order in favor of the long one.…
Quantum oscillation in carrier transport in two-dimensional junctions
Junfeng Zhang, Weiyu Xie, Michael L. Agiorgousis +5
Two-dimensional (2D) device structures have recently attracted considerable attention. Here, we show that most 2D device structures, regardless vertical or lateral, act as a latera…
