摘要
A technique for fabricating Au-rich nanoparticles via phase separation and subsequent oxidation of amorphous Au25Si75 sputtered thin films is presented. Nanoparticles formed in this manner are surrounded by SiO2 and have an average diameter of 2.88 nm with an aerial density of 1.9x10(12) cm(-2). Au-rich nanoparticles are incorporated into capacitor structures and the capacitance-voltage behavior is characterized. Significant hysteresis is observed and the flat-band voltage shift is attributed to charge storage due to the presence of the metal nanoparticles.
