Abstract
The use of Kramers–Kronig transforms is proposed for the treatment of admittance spectroscopy data of junctions when significant shunt conductance or series resistance is present. An algorithm has been implemented to calculate the transformations numerically and the validity of the method developed has been tested using simulated data. Two experimental systems, p‐n junctions into InP made by ion implantation, and atomic‐layer‐epitaxy‐grown CdS/CdTe heterojunctions, have been characterized using this procedure.
