Tóm tắt

This article presents the results of an investigation into defects in synthetic monocrystalline diamond plates after electron irradiation. Data on defect concentration distribution in the infrared (IR) range are given. In addition to IR spectroscopy, positron annihilation spectroscopy (PAS) is used to study the vacancy defects in diamonds. It is shown that PAS using a monochromatic positron beam can be used for the nondestructive control of vacancy distribution along the depth of the diamond plate.
