Abstract:

We propose a novel surface passivation of InP, to obtain the strong luminescence property and completely remove the surface state. InP is passivated by (NH4)₂S solution, then treated by rapid thermal annealing (RTA) at different temperatures. Compared with unannealing sample, the PL intensity is increased to 1.7 times. We adopt atomic layer deposition (ALD) of Al₂O₃ avoiding oxidizing gradually.
