The effect of etchants on surface of CdTe single crystal

Cadmium telluride crystals (CdTe) have been grown by the sublimation method. The crystal polarity of the CdTe with the zincblend structure has been studied. Two different crystallographic defect and etch pits are revealed on the (111) Cd and Â Te surfaces by different etchant.

LiNbO3 (Mg:LN) crystal is an important electro-optical material and MgO-doped LiNbO3 was expected to improve its optical damage resistance. In the present work, we reported the Bridgman growth of MgO-doped LiNbO3 crystal. The growth parameters were discussed and the defects were investigated by the chemical etching method. The etch hillocks and etch pits were observed on the negative Z surface while only etch pits on the positive Z surface by the optical microscope and EPMA. The etching morphology was discussed considering the domain structure.

Sublimation Method

In this study, we suggest the effective enlargement method of (0001) 4H-SiC bulk crystals grown by the sublimation method using long length growth technique (LLG). This method could achieve low thermal strain and rapid enlargement growth comparing with conventional c-axis growth technique. We also demonstrated high quality enlargement growth from 2inch to  4inch of (0001) 4H-SiC by LLG.
