Definitions:

Alkaline

A type of basic, as opposed to acidic, substance; in batteries, it refers to a type using alkaline electrolytes such as potassium hydroxide, known for long life and steady power output.

P-Type

A type of semiconductor material that is doped with elements which create excess positive charge carriers or holes.

N-Type

A category of semiconductor material where the charge carriers are predominantly electrons, achieved by doping the material with elements having more valence electrons than the semiconductor.

Semiconductor Materials

Materials that have electrical conductivity between that of a conductor and an insulator, used in the manufacture of electronic devices, including silicon and germanium.
