Webreverse breakdown voltage is relatively insensitive to the current flowing thought the diode (the reverse current). Zener diodes are designed to operate in the reverse breakdown region ... The Schottky diode turns on at about 0.2 Volts compared to 0.7 Volts for the Si diode and it is characterized by a very fast switching times. The symbol, for ... WebMar 1, 2024 · The Pr-MLV showed a mean Schottky barrier height (SBH) of 0.47 ± 0.03 eV and a mean ideality factor of 1.6 ± 0.2. Below the limit of the breakdown voltage the reverse current could be described by image force lowering and a term that depends linearly on the electric field at the metal/ZnO interface.
