The phase diagram of our model, on the planes of B, versus the other control parameters, as follows. (a) The diagram on the plane of B versus T, with $\tilde{f}=0.96\text{nN}/\mathit{\mu }{\text{m}}^2$ and α = 48 pN/μm < σ/ϕ₀, i.e., adhesion weaker (on average) than the surface tension; T_cr can be considered a good approximation to the critical value of the phase separation even for nonzero B. (b) The same diagram, but this time for α = 64 pN/μm > σ/ϕ₀, i.e., adhesion stronger (on average) than the surface tension, so the phase separation occurs for each temperature. (c) Phase diagram on the plane of B versus α, with $\tilde{f}=0.80\text{nN}/\mathit{\mu }{\text{m}}^2$ and T = 1.01 T₀ > T₀ − ɛ²κ/4, i.e., μ > 0; here, again, there is a region of the mixed state, approximately for α < α_cr. (d) Phase diagram on the plane of B versus α, for T = 0.985 T₀ < T₀ − ɛ²κ/4, i.e., μ < 0; for this temperature, there is always a phase separation. (e) Phase diagram on the plane of B versus $\tilde{f}$, with α = 48 nN/μm and T = 1.01 T₀; only damped waves can exist for these values, and there is also a mixed state for $\tilde{f}<f_{\text{cr}}$. (f) Phase diagram on the plane of B versus $\tilde{f}$, with α = 80 nN/μm and T = 0.98 T₀; only traveling waves can exist for these values, and there is phase separation for all $\tilde{f}$. In both panels e and f, the dashed arrows indicate trajectories of the system when βC₀ is increased, affecting both B and $\tilde{f}$.
