Towards layer-selective quantum spin hall channels in weak topological insulator Bi4Br2I2
Abstract Weak topological insulators, constructed by stacking quantum spin Hall insulators with weak interlayer coupling, offer promising quantum electronic applications through topologically non-trivial edge channels. However, the currently available weak topological insulators are stacks of the sa...
