Nanometer-scale Au quantum dots have been assembled on SiO2 by controlling the reaction of raw matedais to form a citrate Au sol and an aminosilane/dithiol-treated patterned Si wafer. The detailed formation mechanism has been studied. Three gold colloidal particles (-15 nm), aligned in a chain to form a one-dimensional current path, was bridged across an 80-nm gap between source and drain metal electrodes, The device exhibited a Coulomb blockade effect at 33 K. 相似文献
