What happens in the depletion region in reverse bias?
in forward biasing depletion region width decreases and in reverse biasing it increases .
Why charge carriers are not present in depletion region of am pn junction?
depletion region is formed only after recombination of holes and electrons..so in depletion region there are only and only immoble positive and nagative ions...hence,there is no charge carrier..
What is the effect on threshold voltage of a mos capacitor on increasing substrate doping concentration?
The threshold voltage will be increased (in case of an N-Mos), because the charge in the depletion region formed under the channel will be more (high density) and hence gate voltage has to overcome this charge for strong inversion. Vt = (work function difference of gate and substrate) + 2*(substrate Fermi voltage) + (Qd/Cox) Where, Qd = charge in Depletion region in Coulomb Cox = Oxide capacitance
What is the width of depletion region of tunnel diode?
0.1 micron
How depletion width varies with biasing voltage?
when the diode is applied forward bias voltage the width of depletion region gets reduced the barrier voltage decreases there by facilitating the easy exchange of holes and electrons. when the diode is reverse biased the width of depletion region increases there by hindering the flow or exchange of charge carriers.
What is the effect of doping on depletion region?
increases with doping
What is significance of depletion region?
Depletion region is the region where current carriers such as electrons and holes are absent.
Why base spreading resistance is not considered at low frequencies?
Base spreading resistance depends on doping of the p-n junction and also the width of depletion region of the p-n junction. Thats what i knw.
What will happen to the depletion region when the P-N junction is supplied by forward bias?
depletion region will decrease.
What happens in the depletion region in reverse bias?
in forward biasing depletion region width decreases and in reverse biasing it increases .
Why depletion region is small in germanium compared to silicon?
The depletion region is smaller in germanium compared to silicon because germanium has a lower bandgap energy, meaning that charge carriers can easily cross the depletion region and recombine on the other side. This results in a smaller built-in potential and a smaller depletion region in germanium.
How depletion region?
depletion region formed by either side of p&n junctions mobile charges accumulate in that places.Type your answer here...
Why charge carriers are not present in depletion region of am pn junction?
depletion region is formed only after recombination of holes and electrons..so in depletion region there are only and only immoble positive and nagative ions...hence,there is no charge carrier..
Is a depletion region a good conductor?
No, a depletion region is not a good conductor. It is an insulating region formed in a semiconductor material when a voltage is applied, creating a barrier to the flow of current.
Does the atmosphere prevent depletion of the ozone over Antarctica?
The atmosphere does not protect the ozone depletion. It is the region where the ozone depletion occurs.
Where is ozone depletion the highest?
The ozone depletion is highest at the poles. Specially at the Antarctica region.
What is another name for depletion mode transistor?
depletion layer depletion zone juntion region space charge region bipolar transistor field effect transistor variable capacitance diode
