Assembly of Supra Nanoclusters within Crystalline and Amorphous 3-D surfaces

摘要: Publisher Summary Syntheses of nanoclusters can be carried out in a variety ways to give unexpectedly different materials. These have varied structural, optical, and transport properties. Quantum confinement is responsible for many these This occurs when the individual clusters semiconductor are same size or smaller than radius an exciton, which weakly bound electron-hole pair. The motion thus, becomes quantized, leading unusual optical electronic Considerable effort has gone into synthesis quantum confined semiconductors as result their useful interesting done from colloidal solution by molecular beam atomic layer epitaxy. structures formed include wells, dots, wires. In approach, synthesized taking advantage vast internal 3-dimensional surface sieves porous glasses. allows controls not generally available chemistry chapter reviews current methods employed synthesize nanoclusters.
