Trade Cree

Creewas founded in July 1987 in Durham, North Carolina. Five of the six founders — Neil Hunter, Thomas Coleman, John Edmund, Eric Hunter, John Palmor and Calvin Carter — are graduates of North Carolina State University. The company was known for light bulbs, lighting products, energy products and rf. Most of their products are based on silicon carbide (SiC), a mineral compound that early cree researchers successfully synthesized in the laboratory. in 1983, the founders - one of the assistant professors looking for ways to take advantage of silicon carbide properties to enable semiconductors to operate at higher operating temperatures and energy levels. They also knew silicon carbide could act as a diode in light emitting diode (LED) lighting, a light source first shown in 1907 with the electrically charged diode of SiC. Research Team devised a way to grow silicon crystals in the laboratory, and in 1987 founded a company, Cree Research, Inc., to produce SiC and exploit its commercial use in both semiconductor and lighting. The founders raised funds for office and laboratory facilities and entered a period of steady technological progress. In 1989, the company introduced the world's first blue led, which enabled the development of large, full-color video screens and billboards. In 1991, Cree released the world's first commercial silicon carbide chip. In 1993, Cree launched a preliminary public offering.
