GaN Schottky-pn junction diode (SPND)unipolar-carrier-conductionlow turn-on voltageBy introducing a thin p-type layer between the Schottky metal and n-GaN layer, this work presents a Schottky-pn junction diode (SPND) configuration for the GaN rectifier fabrication. Specific unipolar carrier conducti...
Whereas when a forward bias is applied, the depletion region width of the p-n junction diode decreases so the amount of the uncovered space charge decreases as well.So the p-n junction diode behaves as a device in which the amount of charge in the depletion region depends on the voltage ...

5). As the reverse bias increases, W must increase to accommodate the increased charge on each side of the junction. We calculate the junction capacitance, Cj, from the rate of change of charge within W as the voltage is varied. The result is equivalent to the usual parallel-plate ...

In the reverse direction virtually no current flows, but in the forward direction it steadily increases, especially after the knee or turn on voltage is reached. This is modified in the presence of light. When used as a photo-diode it can be seen that the greatest effect is s...
Among all these parameters, the forward voltage of a pn-junction is probably the most widely used parameter for temperature determination of a power semiconductor device. In MOS-gated power devices, gate threshold voltage is an alternative parameter with high temperature resolution. In this work, ...
