Bipolar Transistor

The Bipolar transistor concept

From the last chapter we saw a p-n junction diode which had similar characteristic current-vs- voltage responses when biased either in the forward direction or backward.


Transistor Physical features

The three layers

A transistor has three semi-conductor payers. The three layers occur in the order of

p-n-p= holes-electron-hole

n-p-n= electron-hole-electron


The three layers are formed from a single crystal such that the doping of the single crystal defines the boundaries. The three layers are not "glued" together.
