Influence of Secondary Phases in Kesterite-Cu2ZnSnS4 Absorber Material Based on the First Principles Calculation
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. …”

Effect of phosphorus and gallium on oxidation resistance of Sn-0.7Cu brazing metal: First-principle calculation and experimental verification
Published 2025-03-01“…In this paper, the mechanism of the effect of phosphorus and gallium on the oxidation resistance of Sn-0.7Cu brazing alloy was studied based on the calculation of first principles. The calculation shows that the control principle of the anti-oxidation of phosphorus and gallium is that a passivation film is formed on the surface of the substrate, which prevents the subsequent reaction of oxygen in the air with the substrate. …”

Renormalized Phonon Microstructures at High Temperatures from First-Principles Calculations: Methodologies and Applications in Studying Strong Anharmonic Vibrations of Solids
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. …”
