a The up-up-down trimerization of the terbium sublattice fit to a sinusoid to extract the distortion amplitude (Δ) and phase. b A map of the local distortion amplitude in a 15 nm TbInO3 thin film overlaid on a HAADF-STEM micrograph. c The trimerization phase corresponds to six possible ferroelectric domains. d A map of the improper ferroelectric domains in the same region as (b), based on the color scale given in (c).
