Research Abstract

The growth dynamics of the topological insulator (TI, Bi_2Te_3)films at Si(111)-7x7 has been investigated by using a LEEM. The optimized parameters for MBE growth have been found. The HRTEM results and the transport properties of as-above Bi_2Te_3 films further indicated the interface structure between the film/substrate in real space and insulating-metallic modulation.
