With this in mind, the similarity of the ITO/CdS/PbSe heterojunction with a Schottky diode suggests that the ohmic behavior initially obtained is due to the formation of a tunnel ohmic contact. Figure 8 a shows the suggested energy band diagram for this type of contact, which forms a very narrow potential barrier at the interface, thus allowing ... How does Schottky diode work? In a Schottky diode, a semiconductor-metal junction is formed between a semiconductor and a metal, thus creating a Schottky barrier. The N-type semiconductor acts as the cathode and the metal side acts as the anode of the diode. This Schottky barrier results in both a low forward voltage drop and very fast switching. This work presents a simplified analytical model of a p-n junction diode based on a graphene nanoribbon (GNR) and a unique type of Schottky diode based on metallic graphene and semi-conducting GNRs. The photocurrent generation process of the Au/n-GaSb Schottky PD is illustrated in Fig. 1 (a) with a band diagram. When the light with a shorter wavelength than the bandgap wavelength of the GaSb is absorbed in the active region of the PD, generated electron-hole pairs are converted tothe current.

Schottky Diode. In Schottky diodes, forward voltage is lower than that of other silicon P-N junction diodes. When there is a low current and voltage varies between 0.15 and 0.4 volts, drop in the voltage can be seen. In order to achieve that performance, these are constructed differently. Schottky diodes are widely used in rectifier applications.
