Method for aligning nanowires, 3-dimensional frame for aligning nanowires, and method for 3-dimensional frame for aligning nanowires

摘要

PURPOSE: A method for aligning nano-wires using a groove structure, a three dimensional frame for aligning the nano-wires, and a method for manufacturing the three dimensional frame are provided to efficiently align the nano-wires on a desired position in a nano-wire element manufacturing process. CONSTITUTION: A substrate(201) with a three dimensional structure is prepared. Pluralities of trench grooves, in which both inner walls thereof are inclined, are formed in the three dimension structure. A nano-wires(10) dispersed solution is arranged on the three dimensional structure. The solution is dried to align nano-wires in the trench groove along the longitudinal direction of the trench groove. The trench grooves are parallelly expanded. The cross section shapes of the trench grooves are V-shapes or truncated type inverted pyramid shapes.
