We have developed a compact streak camera suitable for measuring the duration of highly charged subrelativistic femtosecond electron bunches with an energy bandwidth in the order of 0.1%, as frequently used in ultrafast ...

Gold Schottky-barrier diodes ~SBDs! were fabricated on vapor-phase-grown single-crystal ZnO. Deep-level transient spectroscopy, using these SBDs, revealed the presence of four electron traps, the major two having levels ...

Spectral and electrical characteristion of ultraviolet (UV) sensitive photodiodes requires a calibrated optoelectronic system. For spectral characteristion, the irradiance of the UV light source, after the light passed ...
