PRODUCTION OF CDTE SINGLE CRYSTAL

摘要

PURPOSE:To enhance the resistivity and energy resolving power of a CdTe single crystal contg. chlorine by heat-treating the single crystal in vacuum or in inert gas in special conditions. CONSTITUTION:A CdTe single crystal contg. 0.8-5wt.ppm chlorine is successively heat-treated in vacuum or in inert gas at 350-450 deg.C for >=11hr, at 150-350 deg.C for >=20hr and at 50-150 deg.C for >=10hr to obtain a CdTe single crystal having >=5X10<8>OMEGAcm resistivity.
