CdTe SINGLE CRYSTAL AND CdTe POLYCRYSTAL, AND METHOD FOR PREPARATION THEREOF

摘要

Use the 50~200ppmwt chlorine doped polycrystalline CdTe as the raw material , the vertical gradient -free jingbeop horizontal gradient free jingbeop , the vertical bridge maenbeop horizontal bridge maenbeop and Czochralski liquid encapsulation method of any one of the chlorine concentration in the crystal by growing a crystal by a method 0.1~5.0ppmwt, the resistivity at room temperature of 1.0 10 ⁹ and was to manufacture a single crystal CdTe cm or more .
