To confirm such a theoretical prediction, we compared the PL emission of h-BN with AlN, a direct bandgap semiconductor with similar energy bandgap values. Shown in Fig. 5(a) are the PL spectra of h-BN grown by plasma-assisted MBE (Sample C) and a commercial AlN epilayer sample (~4-μm thick, MSE Supplies LLC) measured under the same conditions at room temperature.
