Single crystal A2B6 compounds

Single crystals of II-VI compounds are grown from the vapor phase by physical transport with helium or argon and by chemical transport with hydrogen or argon-hidrogen gas mixture. Types of materials: ZnS, ZnSe, ZnTe, Zn1-xCdxS, Zn1-xCdxSe, CdSxSe1-x. CVD ZnSe for the usage in high power CO2 laser optics has 4 - 6 times lower absorption coefficient at 10.6 µm compared with polycrystalline ZnSe.

At present three types of AIIBVI crystals are growing: ZnSe , CdSe, CdS. From these crystals we can fabricate:
- ZnSe IR optical components, which operate as elements of high power CO2-lasers (windows, lenses, prisms, beamspliters)
- ZnSe oriented single crystals rods as IR electrooptical modulators, any crystallographic orientation, resistivity >1010 Ohm x cm
- ZnSe oriented cubics, high resistivity
- ZnSe substrates to fabricate heterojurunctions with GaAs film (blue light emission diodes and lasers)-plates (111) or (100) orientation, high resistivity, free of twins, EPD is 104/ cm2
- CdS oriented plates with low and high resistivity

Single crystal A2B6 compounds are applicable in areas of research, development, education & production: photonics, optic, laser technology, dosimetry, telecommunications, electronic.
