We investigated moisture and thermal stability of MAPbBr3 perovskite material. Cubic
MAPbBr3 was found to be moisture-insensitive and can avoid the thermal stability issues …

Laser scanning optical beam induced current (OBIC) microscopy has become a powerful
and nondestructive alternative to other complicated methods like electron beam induced …

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 analyzed the carrier lifetime in a drift layer of 1.2 kV-class SiC pn diodes to suppress
bipolar degradation. According to the device simulation results, the required carrier lifetime …

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 …

In recent years, 4H-SiC power devices have been widely employed in power electronic
systems owing to their superior performance to Si power devices. However, stacking faults in …

The purpose of this work is to study the 4H-SiC epitaxial layer properties for the fabrication of
a device for neutron detection as an alternative material to diamond detectors used in this …

Carrier lifetime plays a crucial role in optimizing the performance and reliability of SiC
devices. Surface recombination is one of the factors affecting carrier lifetime. However, the …

The on-resistance of bipolar devices depends on the carrier lifetime, which is determined by
Shockley–Read–Hall, surface, radiation, and Auger recombination processes. Values for the …

In bipolar SiC devices, which are promising under ultra-high voltage operation, the carrier
lifetime is a highly influential parameter for the device performance. Surface recombination …
