FIG. 1.

Micro-PL spectra of diameter reference mesa-structure (without oxidation) for different cw excitation densities: (1) , (2) , (3) , (4) , (5) , and (6) . GS, FES, and SES are denoted as ground, first-excited, and second-excited state transitions, respectively. The inset shows the spectrum of micro-PL on microdisk at . The sample-holder temperature is .
