Abstract

Implantation of 1 × 1018 ions/cm2 of Al at 100 keV into a single crystal of silicon in a 10-8 Torr vacuum system results in the formation of a 0.3 um surface region containing about 50% Al and 50% Si. Transmission electron microscopy studies show that the Al atoms form crystalline Al of grain size about 100 Å, and these grains are embedded in amorphous Si. In contrast to amorphous Si produced by other techniques, the amorphous Si produced by the ion implantation recrystallizes when illuminated with 120 keV electrons.
