Description of this data

Fig. 2. Comparison between Al0.24Ga0.76N band-gap energy and energy spectra of photons emitted from 280- and 310-nm LEDs. The energy spectrum of photons emitted from a blacklight lamp is also drawn in the same figure [22].

Fig. 3. Comparison between F/Ga, N/Ga, and Al/Ga ratios of the as-grown AlGaN surface and the AlGaN surface irradiated for 5 min with CF4 plasma only.

Fig. 4. (a) F/Ga, (b) N/Ga, and (c) Al/Ga ratios of AlGaN surfaces irradiated simultaneously with CF4 plasma and UV at wavelengths of 280 and 310 nm, as a function of UV intensity. The results at an UV intensity of 0 mW/cm2 correspond to those caused by CF4 plasma-only irradiation.

Fig. 5. F 1s regions in XPS spectra of AlGaN surfaces irradiated simultaneously with CF4 and UV at wavelengths of (a) 280 and (b) 310 nm. The results at an UV intensity of 0 mW/cm2 correspond to those caused by CF4 plasma-only irradiation.

Fig. 6. Comparison between CFx fractions of the surfaces irradiated simultaneously with CF4 and UV at wavelengths of 280 and 310 nm, as a function of UV intensity. The result at an UV intensity of 0 mW/cm2 correspond to those caused by CF4 plasma-only irradiation.

Fig. 7. (a) An AFM image and (b) a height profile along a straight green line of AlGaN surface irradiated simultaneously with CF4 plasma and 280 nm-UV at 3 mW/cm2.
