  • OS1120 Electric properties of low-angle grain boundaries in LiNbO_3

抄録

A dislocation in a crystalline material has dangling bonds at its core and strong strain field in its vicinity. Therefore, it has a potential to exhibit peculiar physical properties. In this study, we investigated electric properties of dislocations in lithium niobate. In order to introduce dislocations in the crystal, we fabricated low-angle grain boundaries by a diffusion bonding technique. Owing to this method, we can arrange dislocations periodically in the crystal. It was found that electric properties of dislocations are different depending on the Burgers vector.
