In-Depth Information
The impedance and its evolution with increasing potential observed on and
silicon samples are similar to those on except for the high-frequency loop, loop I,
associated with the space charge layer. For heavily doped and the impedance
associated with the space charge layer is not revealed, indicating that the impedance of
the space charge layer compared to that of the Helmholtz layer is negligible. On the
other hand, for lowly or moderately doped
the impedance in the entire anodic
