Fermi liquids (FLs) display a quadratic temperature (T) dependent resistivity. This can be caused by electron-electron (e-e) scattering in presence of inter-band or Umklapp scattering. However, dilute metallic SrTiO3was found to displayT2resistivity in absence of either of the two mechanisms. The presence of soft phonons as possible scattering centers raised the suspicion thatT2resistivity is not due to e-e scattering. Here, we present the case of Bi2O2Se, a layered semiconductor with hard phonons, which becomes a dilute metal with a small single-component Fermi surface upon doping. It displaysT2resistivity well below the degeneracy temperature in absence of Umklapp and inter-band scattering. We observe a universal scaling between theT2resistivity prefactor (A) and the Fermi energy (EF), an extension of the Kadowaki-Woods plot to dilute metals. Our results imply the absence of a satisfactory understanding of the ubiquity of e-eT2resistivity in FLs.
