Additional information

I proposed to use ternary topological insulators (BixSb1-x)2Te3 to lower the bulk carrier density – excessive bulk carriers deteriorate the properties of the 3D topological insulators – and then planned the experiments with D. Kong and Y. Cui. For the experiments, I systematically characterized the electronics structure of the (BixSb1-x)2Te3 with series of compositions and identify the best one for the transport experiment (performed by D. Kong) and realized the ambipolor gating effect.
