Weak localization

There are many possible scattering paths in a disordered system
Weak localization is due primarily to self-intersecting scattering paths

Weak localization is a physical effect which occurs in disordered electronic systems at very low temperatures. The effect manifests itself as a positive correction to the resistivity of a metal or semiconductor.[1] The name emphasizes the fact that weak localization is a precursor of Anderson localization, which occurs at strong disorder.
