There is another type of breakdown named asavalanche breakdowngenerally seen in the normal diode which requires large amount of reverse voltage to break the junction. Its working principle is when the diode is reverse biased, small leakage currents pass through the diode, when the reverse voltage ...
P-n junction diode is the simplest form of all the semiconductor devices. However, diodes plays a major role in many electronic devices.A p-n junction diode can be used to convert the alternating current (AC) to the direct current (DC). These diodes are used in power supply devices. Wha...
Before discussing Schottky barrier diodes (SBDs), let us learn how a pn junction works since it is the most basic junction for forming a diode. When p-type and n-type semiconductors are joined together, their Fermi levels become equal. This creates a difference in potential...

Diodes:** Have a lower forward voltage drop and are used in high-speed switching applications.- **Photodiodes:** Generate current when exposed to light and are used in light-sensing applications.Each type of diode exploits the properties of the PN junction in different ways to serve specific ...
3) Saturation State (S): Both the emitter junction and the collector junction are forward biased. Working State In Figure (a), when there is no voltage input at b of the NPN transistor, no current flows between c and e, and the triode is in the cut-off state. ...

when sections of n- and p-type material are brought in contact to form a PN junction, a diode is formed. Diodes have a number of interesting and useful properties that are due entirely to the nature of the PN junction.
Effects of surface defects on performance of kV-class 4H– and 6H–SiC epitaxial mesa pn junction diodes were investigated. Mapping studies of surface morphological defects have revealed that triangular-shaped defects severely degrade high-blocking capability of the diodes whereas shallow round pits and...
