High-performance Thermoelectric Monolayer γ-GeSe and its Group-IV Monochalcogenide Isostructural Family
Zheng Shu, Bowen Wang, Xiangyue Cui +4
Recently synthesized novel phase of germanium selenide (γ-GeSe) adopts a hexagonal lattice and a surprisingly high conductivity than graphite. This triggers great interests in expl…
Phononic transport in 1T prime-MoTe2: anisotropic structure with an isotropic lattice thermal conductivity
Xiangyue Cui, Xuefei Yan, Bowen Wang +1
Molybdenum ditelluride (MoTe2) is an unique transition metal dichalcogenide owing to its energetically comparable 1H and 1T prime phases. This implies a high chance of coexistence…
Promoted Electronic Coupling of Acoustic Phonon Modes in Doped Semimetallic MoTe2
Xiangyue Cui, Hejin Yan, Xuefei Yan +2
As a prototype of the Weyl superconductor, layered molybdenum telluride (MoTe2) encompasses two semimetallic phases (1T_prime and Td) which differentiate from each other via a slig…
First-principles Study of Phonon Lifetime and Low Lattice Thermal Conductivity of Monolayer γ-GeSe: A Comparative Study
Bowen Wang, Xuefei Yan, Xiangyue Cui +1
Germanium selenide (GeSe) is a unique two-dimensional (2D) material showing various polymorphs stable at ambient condition. Recently, a new phase with a layered hexagonal lattice (…
Phonon anharmonicity and thermal conductivity of two-dimensional van der Waals materials: A review
Xuefei Yan, Bowen Wang, Yulong Hai +3
Two-dimensional (2D) van der Waals (vdW) materials have extraordinary thermal properties due to the effect of quantum confinement, making them promising for thermoelectric energy c…
Efficient Passivation of Surface Defects by Lewis Base in Lead-free Tin-based Perovskite Solar Cells
Hejin Yan, Bowen Wang, Xuefei Yan +5
Lead-free tin-based perovskites are highly appealing for the next generation of solar cells due to their intriguing optoelectronic properties. However, the tendency of Sn2+ oxidati…
Size and Stoichiometric Dependence of Thermal Conductivities of InxGa1-xN: A Molecular Dynamics Study
Bowen Wang, Xuefei Yan, Hejin Yan +1
The thermal conductivities k of wurtzite InxGa1-xN are investigated using equilibrium molecular dynamics (MD) method. The k of InxGa1-xN rapidly declines from InN (k_InN = 141 W/mK…
