AlGaAs heterojunction visible (700 nm) light-emitting diodes on Si substrates fabricated by metalorganic chemical vapor deposition

Abstract
AlGaAs visible surface light-emitting diodes (LED’s) on silicon substrates have been successfully fabricated by use of the metalorganic chemical vapor deposition technique. The emission spectrum of the LED peaked at 700 nm with a half-width of 45 nm at the forward current of 100 mA at room temperature. The external efficiency was 0.3%.
