(a) Morphologies of diblock copolymer by changing the width of groove with f B = 0.5 and the fixed h = 4.92 R g; (b) the morphologies of diblock copolymer by changing the width of groove with f B = 0.65 and the fixed h = 4.92 R g. From left to right the ratios of h / L of the groove are 4, 2.4, and 1, respectively.
