Abstract
Methods of testing a semiconductor, and semiconductor testing apparatus, are described. In an example, a method for testing a semiconductor can include applying light on the semiconductor to induce photonic degradation. The method can also include receiving a photoluminescence measurement induced from the applied light from the semiconductor and monitoring the photonic degradation of the semiconductor from the photoluminescence measurement.
