Structure of Amorphous Silicon Monoxide

Authors:

Abstract
The pair distribution function in amorphous deposited silicon monoxide has been measured at room temperature. The result is not in good agreement with expectations for a mixture of well‐defined amorphous silicon and amorphous SiO2. Other possibilities, for which the average number of nearest‐neighbor Si–O bonds per atom deviates significantly from 2, can be ruled out. A ring‐type structure, consistent with the diffraction results, and also (apparently) with optical data, is suggested as the most likely alternative.
