Fig. 3: Power spectral densities (PSD) of polystyrene (PS)-air and PS-polymethylmethacrylate (PMMA) interfaces.
From: Impact of noise on spinodal dewetting of liquid-liquid films
PSDs at different dewetting times for a PS-air and b of PS-PMMA interface are obtained from the data displayed in Fig. 2. The corresponding normalized PSD of PS-air and PS-PMMA interface are shown in c, d. Normalization at t is performed with respect to the initial density, i.e., PSD(t, k)/PSD(0, k). The vertical dashed black lines show the local maxima and thin dotted black lines the corresponding errors obtained from full width at half maximum.
