- •
Uniquely ordered Bi2Se0.5Te2.5 pillar array was achieved by an IBAD method.
- •
The pillar array with an ordered lattice field exhibits attractive TE property.
- •
The transport mechanism of such ordered pillar array is proposed and investigated.
- •
Introduction of such ordered lattice field into film is a very promising approach.
