there does not appear to be a correlation of OCP and doping concentration, but OCP
of the (111) orientation is more positive than that of the (100) orientation. Similar
results are reported in another study.

In TMAH solutions,
n-
Si and
p-
Si materials
show similar OCP values and vary little with resistivity from 0.01 to
In solution, OCP of
p-
Si appears to increase with increasing
doping concentration but that of
n-
Si does not reveal such a tendency as shown in
Fig. 2.37.

Examination of the data in Table 2.16 indicates that OCP of silicon electrodes is
in general lower at higher pH values. Figure 2.38 shows that OCP of
p-
Si and
n
-Si
decreases with increasing pH in different solutions.

In 1 M KC
l solutions, OCP of
n
-type silicon follows approximately the Nernst law
up to pH
