It doesn't actually have negative ions, it has majority holes that have recombined with minority electrons, just as the n region has majority electrons that have recombined with minority holes. In both cases are charges are distributed over adjacent atoms and no atom actually becomes either a negative or positive ion.

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 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.
Why a pn junction posses capacitance?
depletion region acts as dielectric between conducting p-plate and n-plate. Note: junction must be in non-conducting state.
What are the types of biasing in pn junction diode?
There are 2 type of biasing in PN junction didoe Forward biasing Reverse biasing
Why tunnel diode are used in negative resistance region?
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
What is depletion region in PN junction?
when the p type semi conductor is connected to n type the electrons in n type migrates towards p type to fill the vacancy i.e holes in p type. As a result accepter ions are developed in n type and donor ions in p type which restrict further movement of electrons and holes . this layer of donor and accepter ions at the pn-junction is called depletion region. and across this region a potential is developed which is called barrier potential.
How depletion region is narrowed during forward biasing?
When the pn junction is forward biased, some of the space charge is neutralized reducing the width of the pn junction.

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........

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
Is Gunn diode a PN junction?
no....is n't
