Photoluminescence (PL) spectroscopy is a powerful tool in studying semiconductor
properties and identifying point defects. Gallium nitride (GaN) is a remarkable …

Carrier dynamics in hydride vapor phase epitaxy grown bulk GaN with very low density of
dislocations, 5–8× 10 5 cm− 2, have been investigated by time-resolved photoluminescence …

Applications of lead halide perovskites in solar cells and photo-and ionising radiation
detectors are based on effective charge carrier generation and transport. The perovskites …

We applied time-resolved pump-probe spectroscopy based on free carrier absorption and
light diffraction on a transient grating for direct measurements of the carrier lifetime and …

Metal halide perovskites are attractive materials for the realization of cheap and effective
solar cells, thin film transistors, and light emitters. Carrier diffusion at high excitations …

The fight against forgery of valuable items demands efficient and reasonably priced
solutions. A security tag featuring holographic elements for anti-counterfeiting is one of them …

We have demonstrated out-of-focus ultrafast pulsed laser processing of copper with a
variable working distance, without the need for mechanical movement. This was achieved …

Time-resolved optical'pump-probe'techniques were applied to monitor carrier dynamics in
CVD-grown 4H-SiC for investigation of carrier diffusivity and recombination rate over a wide …

The diffusion coefficient of holes can provide knowledge about carrier localization in (In, Ga)
N, where the carrier dynamics are altered by randomly fluctuating potential landscape. In …

We demonstrate applicability of time‐resolved free‐carrier absorption and transient grating
techniques for investigation of carrier recombination and diffusion features in a bulk …
