Exciton Fine Structure in Perovskite Nanocrystals [PDF]
The bright emission observed in cesium lead halide perovskite nanocrystals (NCs) has recently been explained in terms of a bright exciton ground state [ Becker et al. Nature 2018 , 553 , 189 - 193 ], a claim that would make these materials the first known examples in which the exciton ground state is not an optically forbidden dark exciton.

Processing and characterization of lead-free ceramics on the base of sodium–potassium niobate [PDF]
Lead-free sodium–potassium niobate-based piezoelectric materials are most intensively studied in order to replace the widely used Pb-based ones. In this work, the effects of modification of compositions by donor and acceptor dopants in the A- and B-sites

Perovskite-polymer composite cross-linker approach for highly-stable and efficient perovskite solar cells. [PDF]
Manipulation of grain boundaries in polycrystalline perovskite is an essential consideration for both the optoelectronic properties and environmental stability of solar cells as the solution-processing of perovskite films inevitably introduces many ...

Electron diffraction of tilted perovskites [PDF]
Simulations of electron diffraction patterns for each of the known perovskite tilt systems have been performed. The conditions for the appearance of superlattice reflections arising from rotations of the octahedra are modified to take into account ...

Mathematical modeling of the perovskite and double perovskite crystal structures
The paper considers the problem of modeling materials with the crystal structure of perovskite and double perovskite. Due to the high complexity of obtaining micro- and nanoscale objects, data on the structure and properties of such materials are especially important.
