    Feb 01, 1997In particular the SF6/O2 sample is interesting since the combination of a high Ge content with a relatively thick reaction layer could lead to enhanced sidewall depletion effects. For this reason the SF6/BHF sample in which the oxidised Ge rich reaction layer has been stripped off, has been taken into account.Cited by: 2
