Size effects on self-assembly and melting of silver-alkanethiolate on inert surfaces by Liang Hu( )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

Self-assembled materials produced in the reaction between alkanethiol and Ag are characterized and compared. It is revealed that the size of the Ag substrate has a significant role in the self-assembly process and determines the reaction products. Alkanethiol adsorbs on the surface of Ag continuous planar thin films and only forms self-assembled monolayers (SAMs), while the reaction between alkanethiol and Ag clusters on inert surfaces is more aggressive and generates a significantly larger amount of alkanethiolate. Two dissimilar products are yielded depending on the size of the clusters. Small Ag clusters are more likely to be converted into multilayer silver-alkanethiolate (AgSR, R = CnH2n+1) crystals, while larger Ag clusters form monolayer-protected clusters (MPCs). The AgSR crystals are initially small and can ripen into large lamellae during thermal annealing. The crystals have facets and flat terraces with extended area, and have a strong preferred orientation in parallel with the substrate surface. The MPCs move laterally upon annealing and reorganize into a single-layer network with their separation distance approximately equal to the length of an extended alkyl chain. AgSR lamellar crystals grown on inert surfaces provide an excellent platform to study the melting characteristics of crystalline lamellae of polymeric materials with the thickness in the nanometer scale. This system is also unique in that each crystal has integer number of layers ⁰́₃ magic-number size (thickness). The size of the crystals is controlled by adjusting the amount of Ag and the annealing temperature. X-ray diffraction (XRD) and atomic force microscopy (AFM) are combined to accurately determine the size (number of layers) of the lamellar crystals. The melting characteristics are measured with nanocalorimetry and show discrete melting transitions which are attributed to the magic-number sizes of the lamellar crystals. The discrete melting temperatures are intrinsic properties of the crystals with particular sizes. Smaller lamellar crystals with less number of layers melt at lower temperatures. The melting point depression is inversely proportional to the total thickness of the lamellae ⁰́₃ the product of the number of layers and the layer thickness

Kinetics and mechanisms of metal silicide formation by Zhiyong Ma( )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

Kinetics and mechanisms of metastable (C49-TiSi$sb2)$ and stable titanium disilicides (C54-TiSi$sb2)$ have been investigated by thermally annealing Ti/polycrystalline Si bilayers using a combination of in situ sheet resistance measurement, in situ stress measurement, x-ray diffraction, transmission electron microscopy (TEM), scanning transmission electron microscopy, and Auger electron spectroscopy (AES). Studies of the initial stage of the C49-TiSi$sb2$ formation during isothermal anneal at 530$spcirc$C and anneal at 10$spcirc$C/m show that the C49 phase first individually nucleates at the interface between amorphous silicide and crystalline silicon, then followed by rapid simultaneous lateral and vertical growth until the formation of a continuous layer of polycrystalline C49-TiSi$sb2.$ Local chemical analysis indicates that the composition range of the amorphous silicide is narrowed due to the appearance of C49 phase. Microstructural study of the C49-TiSi$sb2$ to C54-TiSi$sb2$ polymorphic transformation has been performed to elucidate the microstructural evolution and possible mechanism of the phase transformation. It has been shown that the nucleation of the C54-TiSi$sb2$ is heterogeneous, and preferentially takes place at grain boundaries. The interphase interfaces between C49 and C54 disilicides are often ragged with incoherent characteristics. The growth of the C54 phase is found to proceed by advancing the highly mobile incoherent interfaces in all directions toward the heavily faulted C49 phase. No rigorous orientation relationships are found between two phases. It has been suggested that the C49-to-C54 polymorphic transformation occurs via a massive mechanism. The effect of the C49-TiSi$sb2$ film thickness on the kinetics and mechanism of the C49-to-C54 polymorphic transformation has been studied using in situ resistance measurement, in situ stress measurement, x-ray diffraction, and transmission electron microscopy. The transformation rate is found to be a strong function of the film thickness and temperature, and can be described by exp (E$rmsb a$/kT) with an activation energy of E$rmsb a$ = 3.73, 4.44, and 5.08 ($pm$ 0.07) eV for samples starting with 1000, 550, and 250 A Ti, respectively. An anomalous nucleation-mode transition between nucleation sites, from two-grain junctions (normal grain boundaries) to three-grain junctions (grain edges) is observed as a result of the thickness scaling. The stress measurements show that thin film is under higher tensile stress than thick film after the complete formation of C49-TiSi$sb2.$ It has been suggested that the nucleation of the C54-TiSi$sb2$ is the rate-limiting step in the overall transformation. The observed kinetics difference and nucleation-mode change due to the reduction in film thickness is discussed based upon the energetics consideration of nucleation at different geometrical sites, nucleation site density, and the effects of surface and stress. Evolution of the Ti/a-Ge/Si trilayer reactions has been investigated using TEM and AES. The amorphous phase formation is eliminated by introducing an a-Ge interlayer. The crystalline Ti$sb6rm Gsb5$ is the first phase observed during the reaction. Preceding the equilibrium C54-Ti(Si, Ge)$sb2,$ a substitutional solid solution type C49-Ti(Si, Ge)$sb2$ forms upon annealing at $550sim600spcirc$C, regardless of the replacement of amorphous phase by the crystalline phase. The same type of C49-to-C54 polymorphic transformation occurs at ${sim6}50spcirc$C. The reaction path is also correlated with the change in film resistance obtained from a four-point sheet resistance measurement. (Abstract shortened by UMI.)
