| Research Abstract |
Large scale X-ray imaging detector arrays with energy discrimination capabilities have been studied using single crystal thick CdTe layers grown on Si substrate by metalorganic vapor phase epitaxy. Structure of the detector was high-resistive thick p-CdTe/n-buffer CdTe/n^+-Si substrates. Growth and iodine doping conditions for p-CdTe and n-CdTe layers were established. Pretreatment of Si substrates for high quality CdTe growth was also established.
