METHOD FOR PRODUCING NANOSTRUCTURE, NANOSTRUCTURE, SENSOR, AND SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To deposit a nanostructure of amorphous carbon without restriction of material quality of a substrate on which the nanostructure is grown, and at a low cost.SOLUTION: A method for producing a nanostructure includes: a step to deposit a carbon nanowall layer 230 by growing the carbon nanowall 220 which is a monolayer body or a multilayer body of a graphene sheet such that the carbon nanowall 220 extends to a direction vertical to a surface of a substrate 210 (CNW layer deposition step S110); and a step to heat the carbon nanowall layer 230 with laser irradiation to a temperature higher than the sublimation temperature of the carbon nanowall 220 in an atmosphere to which the carbon nanowall layer 230 is exposed (irradiation step S120).
