Compared to the Ruddlesden–Popper-phase, we find that Dion–Jacobson-phase 2D iodide perovskites have a slower rate of non-radiative carrier recombination.
Hybrid halide perovskites frequently undergo structural expansion due to various stimuli, significantly affecting their electronic properties and in particular charge carrier dynamics. It is essential atomistically model how geometric changes modify characteristics that are important for applications such as light harvesting lighting. Using ab initio simulations, here we investigate the dynamics optoelectronic of FAPbI3 under tensile strain. The applied strain leads elongation Pb–I bonds a...

Metal halide perovskites have recently emerged as one of the most promising classes semiconductors for various applications, especially in field optoelectronics. Lead-based perovskite materials, virtually unexploited decades, become prominent candidates due to their unique and intrinsic physicochemical optical properties. Current challenges faced by scientific community capitalize on properties Pb-based are mainly associated with environmental concerns toxicity Pb poor stability. Under this...
Phase change materials are the most promising candidates for realization of artificial synapsis neuromorphic computing. Different resistance levels corresponding to analogic values conductance can be achieved by modulating size an amorphous region embedded in its crystalline matrix.

Optoelectronic devices based on all-inorganic perovskite systems are an energy-efficient source of lighting due to their high photoluminescence quantum yield (QY). However, dominant surface trapping continues plague the field, despite defect tolerance, as evidenced by several-fold improvements in external efficiency nanocrystals (NCs) upon appropriate passivation or physical confinement between high-band-gap materials. Here, we introduce concept drip-feeding photoexcited electrons from...

The effect of dimensionality reduction on the crystallization kinetics phase change materials is relevant for operation ultrascale memory devices. Therefore, amorphous nanoparticles (NPs) prototypical compounds, GeTe and Ge2Sb2Te5, has been addressed by several experimental works in recent years.
