Bulk Crystal Growth Facility
at Johns Hopkins University
The PARADIM Bulk Crystal Growth Facility is located at Johns Hopkins University. Together with the thin film growth facilities at Cornell, it provides unprecedented capabilities for discovery of new materials and interfaces.
The PARADIM Bulk Crystal Growth Facility is the only facility within the United States where all major optical FZ techniques are available at a single site. In addition, it is the first location in the world to have optical floating zone capability at 300 atm. It is developing the ability to carry out laser pedestal crystal growth in fluids up to 1000 atm of pressure, as well as developing enhanced in situ imaging capabilities (e.g. hyperspectral imaging) to aid and understand growth
