Imaging current distribution in a topological insulator Bi(2)Se(3) in the presence of competing surface and bulk contributions to conductivity

Two-dimensional (2D) topological surface states in a three-dimensional topological insulator (TI) should produce uniform 2D surface current distribution. However, our transport current imaging studies on Bi(2)Se(3) thin film reveal non-uniform current sheet flow at 15 K with strong edge current flow...
