In turn around that is in reverse biased one-sided p-n intersection diode, the positive terminal of the battery is associated with the n-sort semiconductor material and the negative terminal of the battery is associated with the p-sort semiconductor material.
At the point when the outside voltage is connected to the p-n intersection diode such that, negative terminal is associated with the p-sort semiconductor and positive terminal is associated with the n-sort semiconductor, openings from the p-side are pulled in towards the negative terminal while free electrons from the n-side are pulled in towards the positive terminal.
In invert one-sided p-n intersection diode, the free electrons start their excursion at the negative terminal though gaps start their adventure at the positive terminal. Free electrons, which start their trip at the negative terminal, discover vast number of openings at the p-sort semiconductor and fill them with electrons. The iota, which picks up an additional electron, turns into a charged molecule or negative particle or unmoving charge. These negative particles at p-n intersection (p-side) restrict the stream of free electrons from n-side.
Then again, openings or positive charges, which start their voyage at the positive terminal, discover substantial of free electrons at the n-sort semiconductor and supplant the electrons position with gaps. The iota, which loses an electron, turns into a charged molecule or positive particle. These positive particles at p-n intersection (n-side) restrict the stream of positive charge transporters (openings) from p-side.
On the off chance that the switch one-sided voltage connected on the p-n intersection diode is additionally expanded, then much more number of free electrons and openings are pulled far from the p-n intersection. This expands the width of exhaustion locale. Subsequently, the width of the exhaustion area increments with increment in voltage. The wide consumption district of the p-n intersection diode totally hinders the dominant part charge transporters. Henceforth, lion's share charge transporters can't convey the electric current.
Nonetheless, p-n intersection diode permits the minority charge transporters. The positive terminal of the battery pushes the openings (minority transporters) towards the p-sort semiconductor. In the comparative way, negative terminal of the battery pushes the free electrons (minority transporters) towards the n-sort semiconductor.
The positive charge transporters (openings) which cross the p-n intersection are pulled in towards the negative terminal of the battery. Then again, the negative charge transporters (free electrons) which cross the p-n intersection are pulled in towards the positive terminal of the battery. Subsequently, the minority charge transporters convey the electric current in invert one-sided p-n intersection diode.
The electric current conveyed by the minority charge bearers is little. Thus, minority transporter current is considered as insignificant.
