Further indication of a low quartz structure at the SiO2/Siinterface from coincidence Doppler broadening spectroscopy

Brauer, G.; Becvar, F.; Anwand, W.; Skorupa, W.

Results from coincidence Doppler broadening (CDB) measurements on various Si samples and Brazilian quartz having low quartz structure are presented with the aim to give further strong indication of the existence of a low quartz structure, but not of Si divacancies as frequently considered, at the SiO2/Si interface.
