Crystal Growth Laboratory (UVic-CGL)

University of Victoria, Victoria, British Columbia
What the facility does

Materials science and engineering. The facility allows the growth (production) of bulk single crystal materials that have used in various electronic and optoelectronic device developments.

Area(s) of Expertise

The Crystal Growth Laboratory at the University of Victoria has the facilities to bring material production processes from concept to commercial application. The laboratory has growth platforms that cover most crystal growth techniques. The growth of optical, superconducting and semiconductor materials are all feasible. There are a number of growth systems that can be used to grow semiconducting materials like CdTe, CdZnTe, SiGe and GaSb. These materials are used in the development of medical imaging (like gamma detectors as CAT scan, x-ray detectors), security, high mobility and thermal energy conversion devices. The facility also allows to carry out crystal growth experiments under magnetic fields.

In addition to the growth platforms, supporting services covering the refining of materials, large superconducting magnets for simulation of microgravity, rotating magnetic fields for induced stirring, materials preparation and characterization are all available.  All the facilities above can be supplemented with numerical modeling and simulation of the processes. The Laboratory is available for contract work to investigate any of these or related areas. The Laboratory has a strong history of working with industry in the materials-processing sector across a wide variety of subjects. In addition to industry, the Laboratory has provided a wide variety of materials to other researchers in collaboration. Some recent projects have included THM and VGF growth of CdTe and CdZnTe, solidification and structure of aluminum alloys, mass transport in SiGe crystal growth, zone refining of Te, and synthesis of CdTe.
