Abstract :
In this work the 2D dopant profile of a p+n-junction as measured with SCM is compared with the potential contrast maps obtained by scanning electron microscopy (SEM). Two samples prepared by cleaving and by polishing are investigated to quantify the impact of the surface roughness on the accuracy in delineating the junction location.
