Compound Semiconductor Crystals

Cadmium Telluride - CdTe

CdTe and mixed crystals up to 3" diameter for growing epitaxial layers of MCT for IR detectors, special windows, and solar cells. Grown using Bridgeman with Cd-reservoir.

Gallium Antimonide - GaSb

GaSb is available in both P and N types for semiconductor industries. Standard wafers are 1.5, 2.0 and 3.0" diameter and oriented [100], [111] and [311] and off angles. GaSb single crystal wafers are grown by the LEC CZ or horizontal zone melting method and prepared for epitaxial deposition.

Gallium Arsenide - GaAs

GaAs is available up to 3" diameter and can be specially doped for use in microwaves, laser and photoelectric devices. Special single crystal substrates are available for depositing III-V compounds for blue lasers and LEDs.
