Abstract
There are two major problems with the IBIC (ion beam induced charge) t echnique which hampers its wider use for the analysis of semiconductor materials. The small measured charge pulses give a low signal to nois e ratio, and ion induced damage limits the maximum ion dose which can be used to form an IBIC image. This paper investigates the different c harge pulse heights obtained using MeV protons and alpha particles, an d the rate at which the ion induced damage decreases the measured char ge pulse height.
