University of Toronto, Canada

ATC-EP3 MBE System installation in the First Canadian Centre for Advanced Nanotechnology in University of Toronto was successfully completed in 2003. It was deep modernization of EP1203 MBE System produced in USSR.

Results received at that facility are discussed in the following articles:
