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…
Ferroelectricity in 6 Angstrom-Thick Two-dimensional GaO
Tong Jiang, Han Chen, Yubo Yuan +9
Atomic-scale ferroelectric thin films hold great promise for high-density, low-power applications but face stability and voltage scaling challenges at extreme thinness. Here, we de…
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…
