    Influence of Secondary Phases in Kesterite-Cu2ZnSnS4 Absorber Material Based on the First Principles Calculation by Wujisiguleng Bao, Masaya Ichimura

    Published 2015-01-01
    “…The influence of secondary phases of ZnS and Cu2SnS3 (CTS) in Cu2ZnSnS4 (CZTS) absorber material has been studied by calculating the band offsets at the CTS/CZTS/ZnS multilayer heterojunction interfaces on the basis of the first principles band structure calculation. The ZnS/CZTS heterointerface is of type I and since ZnS has a larger band gap than that of CZTS, the ZnS phase in CZTS is predicted to be resistive barriers for carriers. …”

    Renormalized Phonon Microstructures at High Temperatures from First-Principles Calculations: Methodologies and Applications in Studying Strong Anharmonic Vibrations of Solids by Tian Lan, Zhaoyan Zhu

    Published 2016-01-01
    “…The review aims to introduce some recent developements of computational methodologies that are able to efficiently model the strong phonon anharmonicity based on quantum perturbation theory of many-body interactions and first-principles molecular dynamics simulations. The effective potential energy surface of renormalized phonons and structures of the phonon-phonon interaction channels can be derived from these interdependent methods, which provide both macroscopic and microscopic perspectives in analyzing the strong anharmonic phenomena while the traditional harmonic models fail dramatically. …”
