Effects of post-growth annealing on the performance of CdZnTe:In radiation detectors with different thickness

Effects of post-growth annealing on the performance of CdZnTe:In radiation detectors with different thicknessAn effective post-growth annealing method was used to improve the performance of CdZnTe:In (CZT:In) radiation detectors. The results indicated that Te inclusions in CZT:In crystals with different thickness were eliminated completely after annealing. Both the resistivity [...]

Investigation of Te inclusions in CdZnTe crystalline material using Raman spectroscopy and IR techniques

IR images reveal that Te inclusions exist in CdZnTe crystal in the form of square, hexagonal and triangular shapes. The density of Te inclusions for sizes above 5 μm sharply varied from 2.27 × 103 cm−2 to 4.52 × 105 cm−2 with a consequent reduction in IR transmittance from ∼60.5% to ∼55% when the Te-rich volume increased to 83 ppma. Raman spectra suggested [...]
