Despite some fluctuations, E in our study ranges between 10 and 40 kPa, being in the same order of magnitude with

• a different aspect, being more heterogeneous on the MLv domains. This heterogeneity is not clearly correlated to the topographic images. Another example of images of a high-coverage deposit, annealed to 150 °C, is shown in Figure 6. Some well-resolved defects appear in the MLh domain in the upper

• 100 nm. The spectra exhibit emission intermittency, characteristic of single emitters. We observe large variations in the spectra close to the band edge, which represent the individual heterogeneity of the observed quantum dots. We also find specific excitation wavelengths for which the single quantum

• volume. The CAH occurs due to surface roughness and heterogeneity [14][15]. Low CAH results in a low TA, which describes the TA of a surface at which an applied water droplet starts to move [15]. Nowadays, transitional states between the Wenzel and Cassie–Baxter states have been discovered. Wang and
