Property of the phase of the reemitted field in the semiconductor quantum wells (QWs) excited by femtosecond pulse train......

Ultraviolet (UV) detectors with large photosensitive areas are more advantageous in low-level UV detection applications.......

In this Letter, we report large-area (600 μm diameter) 4H-SiC avalanche photodiodes (APDs) with high gain and low dark ......
