Recently both theoretical predictions and experimental investigations have demonstrated that Bi2Te3 is a topological insulator (TI) [1-2].TI is a new state of quantum matter with an insulating bulk gap or gapless edge and current-carrying massless Dirac surface states,and exhibit a rich variety of physical phenomenon such as anomalous magneto-electric coupling and Majorana excitations [3-4].In the present work,few-layer Bi2Te3 nanoplates,which exhibit a variety of morphologies including triangular,truncated triangular,hexagonal and circular shapes,have been synthesized employing vapor-solid mechanism.

当薄膜厚度远小于光学波长时,由于薄膜的表面效应,薄膜的光学常数不仅具有波长色散关系,而且随薄膜厚度改变.对于不同厚度的薄膜,同一波长也会具有不同光学常数.
