“…In order to correlate such behavior with the local U B shifts revealed by IR-LIT, the experimental I-V curves were fitted with the model formed by Eqs. (5)- (7). In this sense, each hot spot (H1, H2 and H3) is considered as an equivalent Schottky diode, connected in parallel to the main diode defined by the more homogeneous Schottky contact.…”
