Charge Loss Between Contacts Of CdZnTe Pixel Detectors

چکیده
The surface of Cd1-xZnxTe (CZT) material has high resistivity but is not a perfect dielectric. Even a small surface conductivity can affect the electric field distribution, and therefore, the charge collection efficiency of a CZT pixel detector. The paper describes studies of this phenomenon for several contact configurations made on a single CZT detector. We have determined the maximum inter-contact separation at which the surface inter-pixel charge loss can be neglected. Corresponding author. E-mail: [email protected]

Direct Conversion CdZnTe and CdTe Detectors for Digital Mammography
Hybrid CdZnTe and CdTe pixel detector arrays with 50 50 micron pixel sizes that convert x-rays directly into charge signals are under development at NOVA for applications to digital mammography. CdZnTe and CdTe have superior x-ray quantum efficiency compared to either emulsion-based film, phosphor-based detectors or other low-Z, solid-state detectors such as silicon. In this paper, latest resul...
متن کاملRecent Progress in CdTe and CdZnTe Detectors
Cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) have been regarded as promising semiconductor materials for hard X-ray and γray detection. The high atomic number of the materials (ZCd =48, ZTe=52) gives a high quantum efficiency in comparison with Si. The large band-gap energy (Eg ∼ 1.5 eV) allows us to operate the detector at room temperature. However, a considerable amount of cha...

Two 3-D position-sensitive semiconductor c-ray spectrometers operable at room temperature, have been fabricated using 1 cm3 cubic CdZnTe crystals. c-Ray spectra have been obtained from 11(x)]11(y)]20(z) voxels, each corresponding to &0.7]0.7]0.5 mm in the detector volume. Individual spectra from each of the 2420 voxels were corrected for electron trapping, di!erences in weighting potentials, an...
