Coupling electromagnetic radiation with matter is promising to tailor optoelectronics properties of functional materials. Here, the authors demonstrate that internal fields induced by coherent lattice motions can be used to control transient excitoni

Humidity can change the properties of halide perovskites used in functional devices. Here, indentation experiments reveal that humidity causes an increase in elastic modulus and a decrease in hardness, which is correlated to bond length, hydrogen bon

Abstract The development of vacuum‐deposited perovskite materials and devices is partially slowed down by the minor research effort in this direction, due to the high cost of the required research tools. But there is also another factor, thermal co

We show a simple modification of spin-coating to obtain pinhole-free, well-covering and uniform films of an all-inorganic Pb-halide perovskite (Pb-HaP), on a flat substrate (i.e., not mesoporous) at standard temperature and pressure. In Pb-HaP-based

Summary: Successful integration of proteins in solid-state electronics requires contacting them in a non-invasive fashion, with a solid conducting surface for immobilization as one such contact. The contacts can affect and even dominate the measured

Summary: Junctions built from metallic nanoparticles (NPs) can circumvent the diffraction limit and combine molecular/nanoelectronics with plasmonics. However, experimental advances in plasmon-assisted electron transport at the nanoscale have been li

Excess lead iodide in the mixed halide perovskites solar cells leads to high device performance but its origin remains elusive. Here Park et al. unveil the underlying microscopic mechanism to be promoting the oriented growth of the perovskites crysta

To experimentally (dis)prove ferroelectric effects on the properties of lead-halide perovskites and of solar cells, based on them, we used second-harmonic-generation spectroscopy and the periodic temperature change (Chynoweth) technique to detect the

We report near-perfect transfer of the electrical properties of oxide-free Si surface, modified by a molecular monolayer, to the interface of a junction made with that modified Si surface. Such behavior is highly unusual for a covalent, narrow bandga
