Great Lakes Crystal Technologies, Inc. is a company that specializes in creating cost-effective high-performance diamond materials for advanced applications. The company is based in East Lansing, MI. The potential for diamond to outperform all other semiconductor materials for a broad range of electronic device applications has been long understood by scientists and engineers due to its fundamental properties. GLCT's mission is to provide a source of these materials, and it was started as a spin-out of the collaboration between Michigan State University and the Fraunhofer USA Center for Coatings and Diamond Technologies. The company was founded in 2019 by Timothy Grotjohn and Keith R. Evans, who has been the CEO since then.
