a Seebeck coefficients (S) measured on NNO films with thickness of 10 nm grown on LAO and STO substrates. b The unstrained film lattice parameter (a0) and c the reversed residual-resistivity ratio (ρ0/ρ300K) of NNO films grown on LAO and STO substrates with different thickness. The error bar was determined from the deviation of repeated measurements.
