| Abstract Scope |
In recent years, it has been found that lowering the dimensionality of halide perovskites has enhanced photoluminescence and stability than its three-dimensional counterpart. Further, the change in the dimensionality of an inorganic halide perovskite can evoke surprising ramifications to its intrinsic behavior. The dimensionality in perovskites is governed from its octahedral cages. In zero-dimension perovskites, the octahedral cages are discrete whereas they are connected with one another forming a layer in two dimension perovskites. Likewise, in three-dimension perovskites, the octahedral cages share the corner atoms with each other. This presentation describes the two-dimensional counterpart of cesium lead bromide perovskites. It presents electronic properties, optical properties and thermoelectric transport properties in conjunction with its three-dimensional structure. The emergence of new physical phenomena with respect to the decreasing dimensionality of cesium lead bromide perovskites are analyzed. |
