Photoluminescence enhancement monitored in real time during photowashing of GaAs

We have observed the luminescence emitted from GaAs during the surface treatment process known as photowashing. This allows us to probe the extent of surface quality improvement in real time as the treatment proceeds. We observe a tenfold increase in photoluminescence (PL) intensity during photowash...
