Patent ID: 7964066

Claim:
A structure control method comprising: measuring a first Raman spectrum of a mixture of nano-scale low-dimensional quantum structures of differing densities of states at a wavelength of an electromagnetic wave with which the mixture of nano-scale low-dimensional quantum structures of differing densities of states is irradiated; irradiating the mixture of nano-scale low-dimensional quantum structures of differing densities of states with the electromagnetic wave in air for two hours after measuring the first Raman spectrum, the electromagnetic wave having an energy density of 10 kW/cm 2 so as to selectively oxidize and remove a low-dimensional quantum structure of a density of states resonating with the wavelength of the electromagnetic wave; measuring a second Raman spectrum of the irradiated mixture of nano-scale low-dimensional quantum structures at the wavelength of the electromagnetic wave; and measuring a reduction in peak intensity of the second Raman spectrum to confirm the selective oxidation and removal from the mixture of the low-dimensional quantum structure.
