Abstract: PURPOSE: A method for changing the light emitting wavelength of multi-layered semiconductor nano-crystal is provided to reversibly change the wavelength by introducing electric charges on the surface of the crystal. CONSTITUTION: Multi-layered semiconductor nano-crystal includes two or more semiconductor layers(10, 20) composed of one or more semiconductor materials. Electric charges are introduced on the surface of or the inside of the multi-layered semiconductor nano-crystal by processing the multi-layered semiconductor nano-crystal with electron donors and acceptors or applying electric filed to the multi-layered semiconductor nano-crystal. Charged electric charges are eliminated.

Abstract: PURPOSE: A semiconductor nanocrystal in which electric charge is introduced on the surface and an optical device including the same are provided to be applied to all kinds of optical devices including an electro-optic modulator by showing reversible change of an emitting wavelength and high photon luminous efficiency when an electric field is applied. CONSTITUTION: A semiconductor nanocrystal in which electric charge is introduced on the surface is a multi-layered semiconductor nanocrystal including two or more semiconductor layers. The semiconductor nanocrystal has one or more interfaces in which a band-gap crosses and the electric charge is introduced on the surface of the semiconductor nanocrystal. A conduction band of a first semiconductor layer(10) is higher than the conduction band of a second semiconductor layer(20). A valence band of the first semiconductor layer is higher than the valence band of the second semiconductor layer.
