We investigate the electronic transport at the internal interface within a selection of metallic bilayer nanostructures using the contact-free, all-optical method of THz time-domain spectroscopy. The Ru/Co, Ru/Pt, and Ru...

Lead halide perovskites were known to be a prospective family of materials for terahertz (THz) generation. On the other hand, perovskite nanostructures, nanoantennas, and metasurfaces allow tailoring perovskites optical ...

Herein we report a facile method for the preparation of hierarchical silica nanostructures through a biomimetic approach. Toward this goal, a protein-directed approach has been proposed to template silica into 3D archite...

Abstract The photocatalytic efficiency of pristine titanium dioxide nanoparticles (TiO2 NPs) remains suboptimal due to its poor visible light absorption and rapid charge carrier recombination, necessitating fine structu...

Monolayer transition metal dichalcogenides (TMDs) possess large second-order nonlinear responses due to the broken inversion symmetry, which can extend their intriguing applications in nonlinear nanophotonics and optoele...

Atomically thin, two-dimensional, transition-metal dichalcogenide (TMD) monolayers have recently emerged as a versatile platform for optoelectronics. Their appeal stems from a tunable direct bandgap in the visible and ne...
