Relations for the Lateral Profiling of Interface States and Fixed Oxide Charge by the Charge Pumping
In this appendix we derive and collect the expressions used in the extraction of
the spatial distributions of interface states 
and fixed oxide charge
from charge-pumping experimental data. Derivations are carried out
on a rigorous footing, without simplifications usually adopted in the
literature. The differentiation of noisy data resulting from the two-dimensional
numerical calculations is addressed briefly. The relationships obtained in
this appendix are employed in Section 3.5.2.
