As shown in Fig. 7(a), the work functions of ZnO and nitrogen-doped carbon (pyridine-N) before contact are 5.28 and 5.84 eV, respectively. When hybridization is formed, a new Fermi level (5.67 eV) is established, which results in the band bending of ZnO and the formation of Schottky barrier at the interface as shown in Fig. 7 (b) [48] .

A quantitative measure of the contact quality is the specific contact resistance, r c, which is the contact resistance of a unit area contact. Depending on the semiconductor material and on the contact quality, r c can vary anywhere from 10-3 Ωcm 2 to 10-7 Ωcm 2 or even less. Fig. 1.

Whenever a metal and a semiconductor are in intimate contact, there exists a potential barrier between the two that prevents most charge carriers (electrons or holes) from passing from one to the other.. Only a small number of carriers have enough energy to get over the barrier and cross to the other material.

The V-I characteristics of Schottky diodes are very much similar to the PN junction diode. Current is the dependent variable while voltage is the independent variable in the Schottky diode. The forward voltage drop of the Schottky diode is low between 0.2 to 0.3 volts. You may also want to check out these topics given below! Semiconductor Diode

Schottky diode is another type of semiconductor diode, but instead of having a P-N junction, Schottky diode has a metal-semiconductor junction and which reduces capacitance and increases switching speed of Schottky diode, and this makes it different from other diodes. The Schottky diode also has other names like surface barrier diode, Schottky barrier diode, hot …
