WebbP-N Junction One of the crucial keys to solid state electronics is the nature of the P-N junction. When p-type and n-type materials are placed in contact with each other, the junction behaves very differently than either type of material alone. Specifically, current will flow readily in one direction (forward biased) but not in the other (reverse biased), …
WebbThe p-n junction receives holes from the cathode terminal, also referred to as the positive terminal. The cathode terminal is the source of holes and the electrons start their … Webb24 feb. 2012 · The PN junction is said to be in reverse biased condition. When there is no voltage applied across the p n junction, the potential developed across the junction is 0.3 volts at 25 o C for germanium on the junction and 0.7 volts at 25 o C for silicon p n junction. The polarity of this potential barrier is the same as the voltage source’s ...

WebbDiffusion capacitance occurs in a forward biased p-n junction diode. Diffusion capacitance is also sometimes referred as storage capacitance. It is denoted as CD. In a forward biased diode, diffusion capacitance is much larger than the transition capacitance. Hence, diffusion capacitance is considered in forward biased diode.
