Volt-ampere characteristic of the double Schottky barrier

open access: yesJournal of Physics and Electronics, 2021
The volt-ampere characteristic (I-V characteristic) of the double Schottky barrier located in the contact region of ZnO grains of zinc oxide based varistor ceramics is calculated using the mechanism of the above-barrier electron emission. I-V characteristic is symmetric to the polarity of the voltage U. At U > 2kBT/e (kB is the Boltzmann constant, T
