A unique PbS structure with necking percolative superlattices was used to study the effects of ligands on the electronic and optoelectronic properties of nanocrystal (NC) solids in order to elucidate the relationship between the NC surface and the properties.

An easily operated, oxalic acid-assisted method was developed for the in-situ fabrication of a three-dimensional (3D) lasagna-like Fe-N-doped carbon nanotubes and graphene hybrid (CNTs-G) framework from a precursor designed at the molecular level. The impressive oxygen reduction reaction performances in both alkaline and acidic conditions confirm the catalytic significance of this technically favorable morphological structure. This work further advances the construction of novel 3D carbon architectures via practical and economic routes.

This article demonstrates the significant enhancement in the optoelectronic performance of WSe2 phototransistors, via in situ surface functionalization with cesium carbonate. The electron mobility of WSe2 was increased by nearly one order of magnitude, while the photoresponsivity and the external quantum efficiency (EQE) were enhanced by almost three orders of magnitude after Cs2CO3 modification.

Partially replacing the organic methylammonium cations by inorganic Cs+ results in perovskite thin films that provide nearly full surface coverage and much higher photoluminescence quantum efficiency due to the greater radiative recombination rate and the smaller nonradiative recombination rate. These films are therefore ideal for electroluminescence applications.
