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-Induced Ferroelectric Phase Transitions
Jiaming Hu, Ziye Zhu, Yubo Yuan +3
Strain-regulated ferroelectric (FE) materials have long attracted significant attention due to their diverse applications. While soft-phonon theory and the (pseudo) Jahn-Teller eff…
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…
Phase engineering of giant second harmonic generation in BiOSe
Zhefeng Lou, Yingjie Zhao, Zhihao Gong +16
Two-dimensional (2D) materials with remarkable second-harmonic generation (SHG) hold promise for future on-chip nonlinear optics. Relevant materials with both giant SHG response an…
