T-square resistivity without Umklapp scattering in dilute metallic Bi2O2Se
Abstract
The electrical resistivity of Fermi liquids usually shows square power law with respect to temperature (T 2) due to either inter-bandscattering or Umklapp process. Here, authors report T 2 resitivity below a temperature where neither Umkapp nor interband scattering is responsible in a dilute metal Bi2O2Se.
