FIG. 11.

(a ) The dependence of chemical potential of the film μ on film thickness l = r − r_p for varied spontaneous curvatures. Curve A, J_r = J_s = 0; curve B, J_r⁼ −1/14 nm⁻¹, J_s = −1/8 nm⁻¹; curve C, J_r = 0, J_s = −1/8 nm⁻¹. The equilibrium width of the film is largest for maximum |J_r − J_s|. (b) The dependence of the boundary energy W (per monolayer)on l. All parameters for curves A – D are the same as in (a). In all curves of panels (a) and (b), h_p = 2.5 nm, h_r = 2.5 nm, h_s = 2.0 nm, r_p = 20 nm.
