Figure 3.12 shows that the COSI mode and the stepping potential mode gener-
ate thicker oxide films than the ramp mode for large samples,

This phenom-
enon is due to the effect of electrolyte resistance, where is the resistivity
of the electrolyte and a is the radius of the sample. It reduces the effective potential
from
to a value lower than 5.5
initially and the initial oxide is grown at lower
