Double perovskite materials have gradually become widely studied due to their potential applications in solar cells and other optoelectronic devices. We take Cs2NaFeCl6 as an example to investigate the carrier mobility with respect to the acoustic ph

This study explores the use of Cu dopant to improve the optoelectronic properties and stability of CsPbX3 perovskites for blue-light-emitting diode material. The addition of Cu causes the metal octahedron of orthorhombic CsPbBr3 to shrink, which rela

Electronic structures and optical properties of Silicon dioxide (SiO2) systems with and without cerium(Ce) dopant were calculated using the density functional theory. We find that after the Ce incorporation, a new localized impurity band appears betw

ELF calculations and COHP analyses confirm that the Cl–Mn bonds in the Cs2AgInCl6:Mn2+ system exhibit more ionic characteristics and stronger bond strengths, which accounts for the blue-shift of the PL peak of Mn ions from Cs2AgInCl6 to Cs2NaBiCl6.

The lead-free double perovskite Cs2AgInCl6 is a potential candidate for LEDs, the photoluminescence performance of which is reinforced greatly by Mn doping. Here, we analyzed the geometric, electronic and photoluminescence properties of Mn-doped Cs2A

To understand the light enhanced moisture degradation of CH3NH3PbI3 (MAPbI3) material, we carry out a series of first principles calculations and find the decisive role played by the giant photostriction effect. The photostriction effect in MAPbI3 ma
