The structure of amorphous Si and Ge

Abstract
Further evidence for the microcrystallite structure of ‘amorphous’ Go films has been obtained from high resolution electron micrographs in which lattice fringes are visible. It is shown that this model is also consistent with the observed diffraction ring patterns from ‘amorphous’ Si if the microcrystals are assumed to be about 14 Å in diameter and to have the hexagonal, wurtzite structure.
