extrinsic semiconductor การใช้

This is an example of an extrinsic semiconductor.
Transistors ( devices that enable current switching ) also make use of extrinsic semiconductors.
Field-effect transistors ( FET ) are another type of transistor which amplify current implementing extrinsic semiconductors.
Pure semiconductors that have been altered by the presence of dopants are known as extrinsic semiconductors [ See : intrinsic semiconductor ].
They are of high electrical resistance higher than typical resistance materials, but still of much lower resistance than doping " ) into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal.
