curves. The peak is sharper and almost one order of magnitude higher for the

type than for the
n
type. The passivation of silicon electrode in other types of alkaline
solutions such as NH

OH, NaOH, EDP, and hydrazine is in general similar to that in
KOH and specific information in these solutions is discussed in Chapter 7. The essen-
tial steps involving passivation have been postulated to be the formation and conden-
sation of surface Si-OH bonds.
