Gold nanoparticles (AuNPs) were grown on a Si(100) substrate using a sacrificial hydrothermal method on Al template prepared by direct current (DC) sputtering, followed by thermal annealing. The effect of annealing temperature on the Al template was investigated. The morphology and phases of the grown AuNPs were observed by field-emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD), respectively. FESEM and XRD results revealed the uniform face-centered cubic structure of AuNPs with isolated 83 nm particle size and 1.48 9 10 13 m -2 area density; these properties were considered optimum for AuNPs formed on the nonannealed sputtered Al template. The electrical properties of AuNPs embedded in polymethylsilsesquioxane (PMSSQ) as an organic dielectric layer were studied using a semiconductor characterization system. A metal-insulatorsemiconductor device with embedded AuNPs was proven to exhibit memory effects. Optimum memory properties of AuNPs embedded in PMSSQ were obtained for AuNPs grown on the non-annealed sputtered Al template with the lowest threshold voltage of 2.4 V in I-V characteristics and 34 electrons stored per AuNP in C-V measurement.

“…[1]. Among these techniques spin coating is superior to grow supported monodispersed nanoparticles in terms of reproducibility, particle uniformity, easily controllable spin coating parameters and cost effectiveness [2,3]. By controlling the stability, size distribution and shape, the surface activity and performance in the targeted applications can be influenced.…”

A surfactant free method for the growth of Ag nanoparticles on glass substrate by spin coating of Ag ions solution followed by chemical reduction in aqueous hydrazine hydrate (HyH) solution has been presented. Appearance of surface plasmon resonance confirms the formation of Ag nanoparticles. Morphology and absorbance spectra of Ag nanoparticles films are used to examine effect of hydrazine concentration on the growth of Ag nanoparticles. SEM images show uniformly distributed Ag nanoparticles. Rate constant was found to be dependent on HyH concentration as a consequence influence particle size.

This work describes the properties of gold nanoparticles (AuNPs) thin film on silicon (Si) substrates. The AuNPs can be divided into two major shapes: gold nanospheres (AuNSs) and gold nanorods (AuNRs). Two sizes of AuNSs (15 nm and 30 nm) and three aspect ratios of AuNRs (3.12, 3.39 and 3.60) were synthesised using the seeding-growth method. The AuNPs produced were deposited on Si substrates by using a spin-coating method followed by heat treatment at 200 C. The number of AuNPs coatings varied as one, three and five coating depositions, respectively. From the field emission scanning electron microscopy, the AuNPs were uniformly distributed on the Si substrate surface. The AuNPs distribution increased with increasing number of AuNPs coating. Various deposited AuNPs with different shapes and sizes were analysed using current-voltage (I-V) measurement in light-dark conditions. The results showed that the resistance of samples became lower under light condition as the number of AuNPs coatings increased on the Si substrate due to the large amount of AuNPs particles, which had better properties in absorbing and scattering the light intensity. Among these samples, five-coating depositions of 15 nm AuNSs and 3.12 aspect ratio of AuNRs thin films gave the best sensitivity in light-dark condition. The higher sensitivity implied the better sensing and recovery properties since it can amplify a small signal from the same light source power/intensity.
