Abstract
Diodes are the basic building blocks of electronic circuits. They are mainly characterized by their current-voltage relation. This relation shows a peculiar behavior, in real-world diodes. That is a non-zero voltage peak in the semi-logarithmic scale in the current. In this brief, a numerical simulation is used to elucidate this phenomenon. It was found that it is due to the different materials used in the diode. If the diode is a homojunction then the peak appears at zero applied voltage while it is displaced if the diode is a Schottky barrier or a heterojunction. This is just an initial work; it requires wider consideration for example narrow band heterojunctions and other diodes made from different semiconductors.
期刊介绍：
Journal of Experimental and Theoretical Physics is one of the most influential physics research journals. Originally based on Russia, this international journal now welcomes manuscripts from all countries in the English or Russian language. It publishes original papers on fundamental theoretical and experimental research in all fields of physics: from solids and liquids to elementary particles and astrophysics.
