    • The GaN surface temperature was monitored using two pyrometers: LEC (KT-PRO) and Chino (IR-AP). ε{lunate} was set to 0.93, which is the value for GaN film reported in Ref. [46]. The difference in the monitored temperatures was less than 50° C. We confirmed the reproducibility of the results using the pyrometers. There was a significant difference in the temperature monitored by the pyrometers and by a thermocouple on the reverse side of a sample mount holder in the TPD measurement. The temperature in TPD appeared to be 100-200° C higher than that in the other measurements. We calibrated the temperature in the TPD curves by the pyrometer values in Fig. 4.

    • TPD measurements were performed at least three times for each type of sample, that is, three different samples cut from the same wafer. We confirmed the reproducibility of the dependence of intensity of each element on the sample weight
