Abstract
We report on some recent results obtained on the analysis of compositional profiles in amorphous hydrogenated silicon structures using a nondestructive nuclear elastic recoil technique (ERD) to profile light elements to a depth of about 1 µm and Rutherford backscattering. We have applied these techniques to the study of the parameters which influence film composition. These include light element contamination, an effect of total thickness on the composition profiles and posthydrogenation. Secondly we have observed the phenomena of interpenetration of elements in multilayer structures. These include dopants in p-i-n junctions and electrode metals. Finally we report modification of concentration profiles by laser annealing.
