A simulation study on bridge defects in lamellae-forming diblock copolymers

In this paper we will describe a self-consistent field theory simulation study on bridge defects in lamellae-forming diblock copolymers. Because the bridge defects are buried three-dimensional defects formed in the diblock copolymer film, it is difficult to observe and determine what causes them. To determine the cause of the bridge defects effectively, self-consistent field theory simulations were used. By reproducing structural characteristics of the bridge defects in the simulation, the cause of the bridge defects were clarified. Finally, we discussed ways to prevent the bridge defects.
