Lattice at low
temperature
As the temperature
rises the atoms vibrate,
acting as though they
are larger.
Lattice at high
temperature
The conduction electrons are scattered by the
vibrating ionic cores and lose some energy to
the phonons, reducing electron flow and
increasing the crystal’s vibrational energy.
The net effect is to convert electrical energy
to thermal energy.
