Figure 8: Interband scattering rate.
From: Heterointerface engineered electronic and magnetic phases of NdNiO3 thin films
Left: interband scattering rate (s−1) in equation (27) versus temperature (in K). T1 and T2 stand for upper and lower part of scaling regime, where relations in equation (30) and equation (31) are satisfied. The plot is obtained for b=c=1. Models with different number of bands lead to shifting of scaling regime. Downward arrows: green arrow denotes upper limit of scaling regime that does not change so much with increasing bands but is suppressed slightly. Above the temperature T1, the resistivity is expected to crossover to TlnT (see equation (29) and discussion immediately below it), consistent with experiment. Blue, purple and brown arrows stand for lower part of scaling regime that are shifted to lower temperature with increasing bands and taking hole-like states as well into account. Right: same as left but with different set of parameters: c=0.28 and b=5.8.
