Fundamental understanding of the correlation between chemical bonding and lattice dynamics in intrinsically low thermal conductive crystalline solids is important to thermoelectrics, barrier coating, more recently photovoltaics. Two-dimensional (2D) layered halide perovskites have attracted widespread attention optoelectronics solar cells. Here, we discover ultralow conductivity (κL) single crystal all-inorganic Ruddlesden-Popper (RP) perovskite, Cs2PbI2Cl2, synthesized by Bridgman method....
Fundamental understanding of the relationship between chemical bonding, lattice dynamics, and thermal transport is not only crucial for thermoelectrics but also essential in photovoltaics optoelectronics. This leads to a widespread search low thermally conductive crystalline metal halide perovskites with improved electrical stability. Pb-free all-inorganic Sn-based are particularly compelling because their degenerate hole doping capability, which generally results p-type conduction. Herein,...

Two-dimensional (2D) lead-free halide perovskites have generated enormous perception in the field of optoelectronics due to their fascinating optical properties. However, an in-depth understanding on shape-controlled charge-carrier recombination dynamics is still lacking, which could be resolved by exploring photoluminescence (PL) blinking behaviour at single-particle level. Herein, we demonstrate, for first time, synthesis nanocrystals (NCs) and 2D nanosheets (NSs) layered mixed halide, Cs3...
Two-dimensional (2D) layered Ruddlesden–Popper (RP) phases of halide perovskite offer exotic properties and interesting structure, which make them suitable candidates for solar photovoltaics, light emitting diodes (LEDs), photodetector applications.
