a,b, Sketch of the trilayer structure (a) and of the annealing protocol (b) in the AFM setup. c, AFM snapshots obtained at 349 K after time t showing the formation and progression of local wrinkles induced by the transformation of the middle TPD layer into a SCL. The bottom graphs show the line profiles of the selected regions. A white arrow marks the pattern considered. Scale bars, 4.0 μm. d, Power spectral density (PSD) distribution of the fully transformed sample indicating the prominent wavelength of the wrinkled distribution. PSD has been calculated with WxSM software with no associated uncertainty. The value of d is determined from the maximum of PSD with an error corresponding to the separation between two adjacent points.
