WebThe electron and gamma irradiation on Schottky contacts have shown zero‒bias offset in the I−V characteristics. The XPS studies revealed that the observed behaviour was mainly attributed to irradiation‒induced defects in n‒4H–SiC bulk and their role in tunneling mechanism rather than contribution from the surface or interface chemical features alone.
