Vf. Reutov et al., Structural modifications in silicon irradiated successively by N+ and He+ or Ar8+ and He+ ions, NUCL INST B, 149(3), 1999, pp. 319-324
The behaviour of He-ion produced radiation defects in crystalline silicon n
ear the interface with an amorphous layer formed by ions of chemically acti
ve (N) and inert (Ar) implants was studied. The TEM-investigation of the st
ructural modifications in Si along the ion beam direction was carried out b
y a novel technique. The boundary of an amorphous layer formed by chemicall
y active nitrogen ions was found to work as a useful getter for radiation d
efects; a property not found after noble-gas implantation. (C) 1999 Elsevie
