چکیده انگلیسی
Infrared (IR) absorption measurements were performed at room temperature on neutron-irradiated type Ib diamonds which contain around 100Â ppm substitutional nitrogen atoms in single form. It was observed that the 1332Â cmâ1 absorption peak appears by irradiation but vanishes again at the dose region higher than 2Ã1018Â n/cm2. This phenomenon is explained by using two-step charge compensation model. Furthermore three remarkable peaks are observed at 1530 and 1570Â cmâ1 and at 1450Â cmâ1. Relations between absorption intensity and neutron dose of these peaks were studied. Intensity of these peaks increase linearly with dose; however, the 1450Â cmâ1 peak intensity saturates around 2Ã1017Â n/cm2 in contrast with the others. These results are consistent with the interstitial models proposed previously.
