Ab initio study of carrier mobility in BiOSe
Yubo Yuan, Ziye Zhu, Jiaming Hu +1
BiOSe is an emerging high-performance layered semiconductor with excellent stability. While experimental studies have explored carrier transport across various doping level…
Quantum Geometric Origin of Strain-Tunable Giant Second-Harmonic Generation in BiOX (X=S, Se, Te)
Zhefeng Lou, Zhihao Gong, Ziye Zhu +3
Two-dimensional (2D) materials with giant nonlinear optical (NLO) responses are essential for the development of advanced on-chip NLO devices. Using first-principles calculations,…
Highly Polarizable Semiconductors and Universal Origin of Ferroelectricity in Materials with a Litharge-Type Structural Unit
Ziye Zhu, Jiaming Hu, Yubo Yuan +3
We discover that a large family of [PbF]- and [BiO]-based mixed-anion materials with a litharge-type structural unit are highly polarizable layered semiconductors o…
Electronic States in One-Dimensional Helical Crystals: General Properties and Application to InSeI
Jiaming Hu, Shu Zhao, Wenbin Li +1
In this article, we systematically explore several key properties of electronic states in helical materials systems, including the inheritance of orbital angular momentum (OAM) fro…
