Epitaxial regrowth of evaporated amorphous silicon by a pulsed laser beam

Abstract
3000‐Å‐thick epitaxial layers of 〈100〉 and 〈111〉 silicon have been grown using a Q‐switched ruby laser. The initial amorphous silicon layers were formed by e‐gun evaporation of high‐purity silicon. Using Rutherford backscattering it was established that the crystal quality of the regrown 〈100〉 Si is much better than the 〈111〉 Si, similar to thermal annealing.
