Any PN junction diode can be used as a variable capacitor in reverse biased mode, as well as in the forward biased mode before the knee voltage. The capacitance is usually very small as the junction ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

This course presents in-depth discussion and analysis of pn junction and metal-semiconductor contacts including equilibrium behavior, current and capacitance responses under bias, breakdown, ...

The relative spin direction between two electrodes determines how much capacitance is present at the junction. "We used iron for one electrode and iron oxide for the other," Xiao said. "The electrical ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

For the first time, researchers demonstrate a new type of magnetocapacitance, a phenomenon that could be useful in the next generation of 'spintronic' devices. Capacitors, electronic components that ...
