Nanomanipulation of single nanowires on structured surfaces fabricated by laser interference lithography

Nanomanipulation is an important technology to fabricate and assemble nanostructures, especially for the asymmetrical structures. This paper presents a method of manipulation of single nanowires on structured surfaces by nano grippers in a scanning electron microscope (SEM). In the method, the structured surfaces of substrate were fabricated by two-beam laser interference lithography. Single nanowires were manipulated on the structured surfaces by nano grippers in the SEM. The method uses a pattern to solve the problem that a single nanowire is too tiny to be picked up and manipulated with nano grippers.
