Webb9 okt. 2024 · The depletion region consists of immobile charge carriers. So on the p side, these are the electrons that are loosely bound to the crystal lattice. On the n side, these are the holes that are loosely bound to the crystal lattice, i.e. the positively charged ionized dopants left behind from those electrons injected into the p side during the formation of … Webb17 maj 2016 · \$\begingroup\$ The electrons in the semiconductor need a little kick to get moving. There will always be some electrons that have enough energy to jump up over the band gap (thermal energy gives a little push on top of the bias voltage). 0.7V is the point at which the vast majority of electrons have enough energy to jump the gap, some will …

Webbstate, the voltage drop across the drain and source is sustained by the PN junction at reverse bias, and a very small current (leakage) flows through the junction. If the voltage increases too much and the electrical field reaches the critical value, the junction goes into breakdown, and the current starts to flow through the body region.
