Which junction has least junction capacitance?
point contact has the least junction capacitance
Why is that a space charge region in a pn junction at equilibrium is often made small?
The space charge region in a pn junction at equilibrium is often made small due to:to obtain a high junction capacitance;since the junction capacitance is inversely proportional to the width of the space charge region, the smaller the width, the larger the junction capacitance.to ensure easy diffusion of charge carriers;if the space charge region is made small, that is, the width is made small, the distance for diffusion also becomes short, then it becomes easy for the electrons to diffuse into the p-side and the holes into the n-side
What is Another name for pn junction?
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
What is the junction resistance of pn junction diode?
The resistance of a forward biased pn junction is zero.
What are the types of biasing in pn junction diode?
There are 2 type of biasing in PN junction didoe Forward biasing Reverse biasing
Which junction has least junction capacitance?

What is pn junction capacitance?
The charge inside of a p-n diode with a connected voltage variety yields a capacitance is need to add circuit model of a p-n diode. The capacitance connected with the charge variety in the exhaustion layer is known as the intersection capacitance, in the same process capacitance connected with the abundance bearers in the semi impartial district is known as the dissemination capacitance.
How a pn-junction can be formed?
A pn junction can be formed by bringing the p and n type materials together.

Why pn junction is neutral?
the material in which using for doping is already neutral.,,so the pn-junction diode also neutral........

Are junction capacitance and transition capacitance the same?
Junction capacitance is used to take the ripple out of DC circuits primarily. The other is used in voltage doublers or step ups as a storage.
Is Gunn diode a PN junction?
no....is n't
How many PN junction are there in FET?
One
What is diffusion capacitance in pn junction?
A capacitor is a device that stores charge. Therefore any device that stores charges( static or dynamic) can be said to have capacitance. When a PN diode is forward biased, a current flows due to the majority charge carriers. At a particular instant there will be charges in motion. This is dynamic charge. The capacitance due to storage of dynamic charge is called the diffusion capacitance. We know that C = Q * V. That is capacitance is directly proportional to charge stored. Since the diode current increases exponentially with the voltage applied across it, the dynamic charge also increases exponentially . Hence the diffusion capacitance increases exponentially with the increasing diode voltage.
