With forward bias, the depletion region is narrow enough that electrons can cross the junction and " inject " into the p-type material.
12.
The capacitance of a PN diode between anode and cathode is inversely proportional to the reverse voltage, growing as it approaches zero volts and into forward bias.
13.
Energy level diagrams for thermionic diode in " forward bias " configuration, used to extract all hot electrons coming out from the emitter's surface.
14.
As noted above, this photo voltage also forward biases the junction, and so " reduces " the pre-existing field in the depletion region.
15.
The minority carrier traps can be also observed for the p-n junctions by application of forward bias pulses, which inject minority carriers into the space charge region.
16.
Hole concentration is accumulated at emitter side in n-base layer because of impossibility of the hole flow through forward bias collector-base junction of the pnp transistor.
17.
The diode prevented the transistor from saturating by minimizing the forward bias on the collector-base transistor junction, thus reducing the minority carrier injection to a negligible amount.
18.
To improve the sensitivity of some of the early crystal detectors, such as silicon carbide, a small forward bias voltage was applied across the detector by a battery and potentiometer.
19.
For example, the internal structure of an NPN forward bias is placed on this junction it will form a parasitic diode structure, and current will flow from base to collector.
20.
Under a forward bias of 1 mA ( the " on " state ), a typical PIN diode will have an RF resistance of about, making it a good RF conductor.
