Localised vibrational mode spectroscopy studies of self-interstitial clusters in neutron irradiated silicon

Abstract: The evolution of self-interstitial clusters in silicon (Si), produced by fast neutron irradiation of silicon crystals followed by anneals up to 750 C, is investigated using localised vibrational mode spectroscopy. A band at 582 cm À1 appears after irradiation and is stable up to 550 C was attributed to small self-interstitial clusters (I n , n 4), with the most probable candidate the I 4 structure. Two bands at 713 and 758 cm À1 arising in the spectra upon annealing of the 582 cm À1 band and surviving up to $7… Show more

“…[1][2][3][4][5][6][7][8][9][10][11] Investigating small self-interstitial clusters in Si is technologically important as they play fundamental role in many solid-state processes affecting the mechanical and electrical properties of the material. It is therefore necessary to control them as their formation can cause detrimental effects.…”
