p-n

Phosphorous is then diffused onto one side to create an n-type semiconductor layer and a p-n junction where the two semiconducting surfaces meet.

When the two types of semiconductors are placed next to one another they form a p-n junction where holes drift from the p-side to the n-side and free electrons drift in the other direction.

These create a dipole layer at the junction that produces an electric field that opposes more majority carriers traveling to the opposite side of the p-n junction.

This free electron is then pulled by the electric field of the depletion region across the p-n junction.

The cell now has a p-n junction, but can only generate an electrical current if it is connected to a circuit.

It is easy to see that the second series is repeated at the beginning of the forth series with the only difference that in the forth series silicon is alloyed with boron and phosphorus, i.e. 'p-n transition' of a diode is created.

They're why, for example, p-n junctions can act as rectifiers and (very important) as transistors.

What a contrast to the elaborate, painstaking creation of p-n junctions in crystalline silicon: it's nice that _one _fabrication issue, at any rate, is far easier!

Since that time I have been keeping, as a most precious thing, my laboratory daily report book that contains notes of mine about the creation of the first soviet p-n junction transistor on the 5th of March, 1953.

It was a very important problem to be solved by our not very big team: creation of germanium diodes and triodes (transistors) on p-n junctions.
