Electronics I - Lecture Notes

Flashcards covering key vocabulary and concepts related to semiconductors and their properties from the lecture notes on Electronics I.

Semiconductors

Elements with conductivity between a good conductor and an insulator.

Intrinsic Semiconductors

Undoped semiconductors that exist in their pure state.

Extrinsic Semiconductors

Doped semiconductors that have specific impurities added.

Valence Electrons

Electrons located in the outermost shell of an atom.

Covalent Bond

A type of chemical bond where atoms share electrons.

Energy Bands

Ranges of energy that electrons can occupy in a solid.

Intrinsic Carrier Concentration

The equal concentration of electrons and holes in an intrinsic semiconductor.

n-type Semiconductor

A semiconductor that has been doped with group V elements, which donate electrons.

p-type Semiconductor

A semiconductor that has been doped with group III elements, which accept electrons.

Doping

The process of adding impurities to semiconductors to change their electrical properties.
