Matthiessens rule

r=rP+rD
ρ: Resistivity
ρP: Phonon contribution of resistivity
ρD: Defect contribution of resistivity


Information:
Category:Solid state physics
Discoverer:Matthiessen
Description:The resistivity in a metal is composed by a defect governed part and a temperature dependent phonon governed part.
