Doubling Up LED Output

February 1, 2011 | 2 Comments

Dr. Salah Bedair, a professor of electrical and computer engineering at North Carolina State University and co-author materials science professor Nadia El-Masry have developed a new LED building technique that reduces defects in the gallium nitride (GaN) films used to create LEDs, making them more efficient. Bedair explains, LED lighting relies on GaN thin films […]
