When a depletion region of a transistor is large the barrier voltage is also large.
The number of electrons in the outer shell of carbon, germanium, and silicon is 5.
The first transistor was invented in 1938.
A covalent bond is when atoms lose valence shell electrons.
Germanium is the most widely used semiconductor material because of its stability at high temperatures.
The n-type semiconductor material is doped by adding material with electron holes.
The P-N junction is a barrier to electron flow.
The forward voltage drop for a germanium transistor is 0.7 V and for a silicon transistor is 0.3 V.
