Impacts of hydrogen annealing on the carrier lifetimes in p-type 4H-SiC after thermal oxidation Open
Thermal oxidation and hydrogen annealing were applied on a 100 μm thick Al-doped p-type 4H-SiC epitaxial wafer to modulate the minority carrier lifetime, which was investigated by microwave photoconductive decay (μ-PCD). The minority carri…

The Dawn of Lead‐Free Perovskite Solar Cell: Highly Stable Double Perovskite Cs<sub>2</sub>AgBiBr<sub>6</sub> Film Open
Recently, lead‐free double perovskites have emerged as a promising environmentally friendly photovoltaic material for their intrinsic thermodynamic stability, appropriate bandgaps, small carrier effective masses, and low exciton binding en…
