Vertically aligned ZnO/CdTe core-shell nanocable arrays-on-indium tin oxide (ITO) are fabricated by electrochemical deposition of CdTe on ZnO nanorod arrays in an electrolyte close to neutral pH. By adjusting the total charge quantity applied during deposition, shell thickness can be tuned from several tens hundreds nanometers. The shell, which has a zinc-blende structure, is very dense and uniform both radially along axial direction nanocables, forms intact interface with wurtzite core....

Abstract 1D nanowires of all‐inorganic lead halide perovskites represent a good architecture for the development polarization‐sensitive optoelectronic devices due to their high absorption efficient, emission yield, and dielectric constants. However, among as‐fabricated perovskite with lateral dimensions hundreds nanometers so far, optical anisotropy is hindered rarely explored owing invalidating electrostatic mismatch in physical dimensions.
