We developed lead halide perovskite quantum dot (QD) films with tuned surface chemistry
based on A-site cation halide salt (AX) treatments. QD perovskites offer colloidal synthesis …

Terahertz spectroscopy has been used for almost two decades for investigations of
nanomaterials, including nanocrystals, nanoparticles, nanowires, nanotubes or 2D crystals …

We explore ultrafast carrier dynamics and interactions of photoexcited carriers with lattice
vibrational modes in BiVO4 photoanode material using time-resolved terahertz spectroscopy …

We report size-dependent exciton formation dynamics within colloidal silicon quantum dots
(Si QDs) using time-resolved terahertz (THz) spectroscopy measurements. THz …

One-dimensional periodic surface structures were formed by femtosecond laser irradiation
of amorphous hydrogenated silicon (a-Si: H) films. The a-Si: H laser processing conditions …

We have used time-resolved terahertz spectroscopy to study microscopic photoconductivity
and ultrafast photoexcited carrier dynamics in thin, pure, non-hydrogenated silicon films …

Nonradiative Auger recombination in multiply excited nanocrystals is a dominant efficiency
loss pathway for nanocrystal-containing optoelectronic devices that rely on high-rate …

Usually, the conductivity of semiconductor can be increased after phosphorus (P) doping but
the electron mobility will be obviously reduced due to the strong impurity scattering. Here …

We demonstrate that in nanostructured films of nanocrystalline silicon imbedded in a
hydrogenated amorphous silicon matrix, carriers generated in the amorphous region are …

We simultaneously determined the charge carrier mobility and picosecond to nanosecond
carrier dynamics of isolated silicon nanowires (Si NWs) and nanocrystals (Si NCs) using …
