PHONON DRAG EFFECT AND DETECTION PERFORMANCE OF GAMMA RAYS IN p-CdTe

Světla Vacková - Vladyslav Gorodynskyy - Karel Žďánský - Karel Vacek

   Cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) are regarded as promising materials for the exploitation in imaging detectors for X-ray and gamma ray spectroscopy, not only in high- energy physics but also in astrophysics, medicine and ecology. There are at least two good reasons for such expectations, namely the high atomic numbers in comparison with for instance Si (ZCd = 48, ZTe = 52) and the large band gap (Eg = 1,5 eV), which allows to operate the detector at room temperature.

Keywords: X-ray, gamma ray spectroscopy, Cadmium telluride, radiation detectors
