a The open-aperture Z-scan plots of Cu-HHTP[001] and Cu-HHTP[100] films. b Variation in the normalized transmittance as a function of input fluence. c The curves of output fluence versus input fluence. d The third-order nonlinear absorption coefficient (β) of Cu-HHTP[001] and Cu-HHTP[100] films. e The calculated third-order polarizabilities (γ) of Cu-HHTP along [001]- and [100]-orientations. The holes (blue) and electrons (green) distribution models of Cu-HHTP along f [001]- and g [100]-orientations.
