Great Lakes Crystal Technologies (GLCT) produces single-crystal high-performance diamond plates, substrates, and epitaxial wafers for applications in electronics, quantum sensing, advanced packaging, and detection. The company designs and builds proprietary chemical vapor deposition (CVD) diamond crystal growth reactors entirely in the U.S. and is the only 100% U.S.-based device-ready single-crystal diamond material manufacturer of its kind. GLCT holds a licensed portfolio of 10 issued and 4 pending diamond materials technology patents from Michigan State University. Founded in 2019 as a Michigan State University startup, GLCT has acquired over $20M in federal investments to expand its product roadmap. The company plans to use new funding to advance manufacturing readiness and develop a prototype of a large-area, high-performance single-crystal diamond substrate for quantum sensing, thermal management in microchip packaging, and advanced electronics within 18 months.
