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…
Microscopic Theory of Light-Induced Coherent Phonons Mediated by Quantum Geometry
Jiaming Hu, Zhichao Guo, Wenbin Li +2
Light-induced coherent phonons provide a powerful platform for ultrafast control of material properties. However, the microscopic theory and quantum geometric nature of this phenom…
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…
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…
