For example, the current near the depletion region of a p n junction is dominated by the diffusion current.
22.
When a photon of sufficient energy enters the depletion region of the diode, it creates an electron, avalanche multiplication.
23.
A junction diode cannot function when the depletion region is bigger than current and functions like an open or closed switch.
24.
The depletion region is not symmetrically split between the n and p regions-it will tend towards the lightly doped side.
25.
As a result a few micrometer thick high-impedance depletion region is developed at the bond barrier in the glass wafer.
26.
At the middle of the junction of the p n material, a depletion region is created to stand-off the reverse voltage.
27.
By bringing up the depletion region, the questioner is implying that the diode is in a circuit and has current passing through it.
28.
This region where electrons and holes have diffused across the junction is called the depletion region because it contains practically no mobile charge carriers.
29.
The emitter-base Zener diodes can handle only smaller currents as the energy is dissipated in the base depletion region which is very small.
30.
A more complete analysis would take into account that there are still " some " carriers near the edges of the depletion region.
