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

Abstract

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.
