What can a semiconductor sense?
Ionization within a P-N junction causes a layer on each side of the barrier called the:
The first transistor was invented in 1938.
The n-type semiconductor material is doped by adding material with electron holes.
Reverse bias is a condition that essentially ___________ current through the diode.
The forward voltage drop for a germanium transistor is 0.7 V and for a silicon transistor is 0.3 V.
Minority carriers are many times activated by:
A P-N junction mimics a closed switch when it:
Elements with 1, 2, or 3 valence electrons usually make excellent:
When an electron jumps from the valence shell to the conduction band, it leaves a gap. What is this gap called?
