INFLUENCE OF THE ATOMIC MASS OF BOMBARDMENT IONS ON THE FORMATION OF DEFECTS IN SILICON CRYSTALS
The fluence of the mass of bombardment atoms on the formation of defects and there clusters on the surface of Si crystals using the SIMS and SRIM methods is investigated. It is shown that the formed interstitial defects on the surface lead to the sputtering of cluster ions, and vacancies affect the...
