Self-assembled morphologies of symmetric diblock copolymers confined in channels with ellipse-shaped cross sections as a function of D e y / L L with (a) D e x / L L ≈ 2, α = 0; (b) D e x / L L ≈ 2, α = 1; (c) D e x / L L ≈ 2, α = 0.1; (d) D e x / L L ≈ 1.5, α = 0.1; and (e) D e x / D e y ≈ 1.5, α = 0.1.
