Abstract :
A reliable 877-nm InGaP-GaAs light-emitting diode (LED) is grown on a Si substrate by metalorganic chemical vapor deposition. A conventional Al-contained AlGaAs-GaAs LED on a Si substrate exhibits a rapid degradation because of formation of dark-line defects (DLD´s). On the contrary, an Al-free InGaP-GaAs LED on a Si substrate has no significant growth of DLD´s, As a result, a stable operation for more than 1500 h has been achieved in an InGaP-GaAs LED on a Si substrate.<>
