“…Level T 1 with the activation energy of about 0.054 eV is assigned to shallow donor, originated from Indoped point defect, which has also been observed in CdTe:In and CdZnTe:In [17,18]. Trap levels T 2 , T 3 and T 4 with the activation energies 0.089 eV, 0.110 eV and 0.139 eV are recognized as shallow acceptors related to A-center and corresponding to first ionization energy of Cd-vacancy according to the theoretical calculations [18][19][20][21][22]. Trap T 5 with the activation energy 0.164 eV is also recognized as A-center [19].…”

“…This effect has been clearly demonstrated [14]. However, the calibration measurements indicated that the CZT detectors did not show any measurable degradation of the energy resolution after about 1 month of operation at ISIS, corresponding to a fast neutron flux of about 10 10 n cm À2 : Much larger fast neutron fluxes ð> 10 12 n cm À2 Þ are known to be required to provide significant deterioration of the detector response [25].…”

The Resonance Detector Spectrometer was recently revised for neutron spectroscopic studies in the eV energy region. In this technique one makes use of a photon detector to record the gamma emission from analyser foils used as neutrongamma converters. The pulse-height response of a Cadmium-Zinc-Telluride photon detector to neutron capture emission from 238 U and 197 Au analyser foils was characterised in the neutron energy range 1-200 eV: The experiment was performed on the VESUVIO spectrometer at the ISIS neutron-pulsed source. A biparametric data acquisition, specifically developed for these measurements, allowed the simultaneous measurements of both the neutron time of flight and g pulse-height spectra. Through the analysis of the g pulse-height spectra the main components of the signal associated with resonant and non-resonant neutron absorption were identified. It was also shown that, in principle, energy discrimination can be used to improve the signal to background ratio of the neutron time-of-flight measurement. r

“…Due to its mechanical and physical properties the CdTe is widely used material. Therefore, in the recent years the CdTe sensors were subject of study of their basic characteristics, effects of different types of radiation (gamma, electrons, positrons, protons, neutrons) [1,2,3,4,5,6] etc. However the manufacturing technologies of CdTe crystals are continuously improving, with results in larger detectors with more uniform response and better radiation hardness.…”

Cadmium Telluride (CdTe) is a compound semiconductor with a large atomic number. It has a large photon absorption cross section in comparison with the silicon and germanium and due to it's large bandgap width it can be operated at room temperature. These properties predetermine CdTe to wide range of applications: from medical and industrial radiographic imaging to space sciences. In this paper, several characteristics of a commercially available CdTe sensors from two manufacturers were compared. The CdTe sensor samples were subject of measurement of their basic electronic characteristics at different temperatures ranging from -40 to +40 • C. Additionally, the effects of 60 Co gamma iradiation up to a dose of 100 kGy were studied at room temperature.
