Pressure-induced metal-insulator transition in oxygen-deficient LiNbO-type ferroelectrics
Chengliang Xia, Yue Chen, Hanghui Chen
Hydrostatic pressure and oxygen vacancies usually have deleterious effects on ferroelectric materials because both tend to reduce their polarization. In this work we use first-prin…
First-principles study on the chemical decomposition of inorganic perovskites \ce{CsPbI3} and \ce{RbPbI3} at finite temperature and pressure
Un-Gi Jong, Chol-Jun Yu, Yun-Hyok Kye +3
Inorganic halide perovskite \ce{Cs(Rb)PbI3} has attracted significant research interest in the application of light-absorbing material of perovskite solar cells (PSCs). Although th…
Critical role of water in defect aggregation and chemical degradation of perovskite solar cells
Yun-Hyok Kye, Chol-Jun Yu, Un-Gi Jong +2
The chemical stability of methylammonium lead iodide (\ce{MAPbI3}) under humid conditions remains the primary challenge facing halide perovskite solar cells. We investigate defect…
Liquid-like thermal conduction in a crystalline solid
B. Li, Y. Kawakita, Q. Zhang +14
A solid conducts heat through both transverse and longitudinal acoustic phonons, but a liquid employs only longitudinal vibrations. Here, we report that the crystalline solid AgCrS…
