Method for controlling structure of nano-scale substance, and method for preparing low dimensional quantum structure having nano-scale using the method for controlling structure

Abstract

A method for controlling a structure of a nano-scale substance may include irradiating a mixture of low-dimensional quantum structures having a nano-scale with an electromagnetic wave in an oxygen atmosphere, to thereby selectively oxidize a low-dimensional quantum structure having a density of states resonating with the electromagnetic wave used for the irradiation. The method allows a low-dimensional quantum structure having a specific structure to be selectively removed from the mixture of low-dimensional quantum structures having a nano-scale.

1 . A producing method of a nano-scale low-dimensional quantum structure, the method comprising:
 irradiating a mixture of nano-scale low-dimensional quantum structures of differing densities of states with an electromagnetic wave in an oxygen atmosphere, so as to selectively oxidize a low-dimensional quantum structure of a density of states resonating with the electromagnetic wave and thereby retain a structure with a density of states not resonating with the electromagnetic wave.
