In this work, main characteristics are considered of photosensitive Schottky diode structures – n-type ZnSe(Te,X)/Ni, where Х = O or Al, which are promising as ultraviolet radiation detectors in the 200–480 nm range. The Schottky barrier-based s

A large-area X-ray CMOS image sensor (LXCIS) is widely used in mammography, non-destructive inspection, and animal CT. For LXCIS, in spite of weakness such as low spatial and energy resolution, a Indirect method using scintillator like CsI(Tl) or Gd2

Presently, most X-ray security systems for luggage inspection use dual-energy detector. A drawback of this approach is that overlap in energy sensitivity of the low- and high-energy detectors creates the potential for ambiguity and inaccuracy. We hav
