Buffer-Layer-Assisted Growth of Nanocrystals: Ag-Xe-Si(111)
نویسندگان
چکیده
Silver nanocrystals have been grown on Xe buffer layers at 50 K. These 3D nanocrystals are delivered to Si(111)-s7 3 7d surfaces when the Xe layer is desorbed, but the density observed on the surface depends strongly on the buffer layer thickness. This dependence reflects an unusual desorption-assisted coalescence process. The results suggest that buffer-layer-assisted growth can be used to prepare nanocrystals of different sizes for a wide variety of materials and substrates. [S0031-9007(98)05945-6]

Ag buffer layer effect on magnetization reversal of epitaxial Co films
Nano-sized Ag(111) islands were first prepared by using molecular beam epitaxy technique on dilutedhydrofluoric acid etched Si(111) substrate. Epitaxial Co films were then grown onto the Ag films at 100 °C to decrease interdiffusion. The Ag buffer layer designed to form isolated islands with {111} sidewalls on the Si(111) substrate, and provided Co films (111) texture growth to study the correl...
متن کاملSubstrate dependent buffer-layer assisted growth ofnanoclusters
The role of the substrate on the morphology of nanometer size clusters fabricated by buffer layer assisted growth (BLAG) was studied using scanning tunneling microscopy. Clusters of Fe and Co were deposited on Ag(111), Cu(100), Rh(111), and Pt(111) surfaces using identical BLAG parameters, which are temperature, as well as metal and buffer layer coverage. Semi-hemispherical clusters are found o...
متن کاملSize- and shape-dependent energetics of nanocrystal interfaces: experiment and simulation.
We study the interface energetics of Ag nanocrystals on a H-passivated Si(111) surface by a transmission electron microscopy experiment and molecular dynamics simulations. The annealed nanocrystals are oriented with Ag(111)||Si(111). Azimuthally, epitaxy is preferred for nanocrystals with an interface larger than a coincident-site-lattice (CSL) cell. The equilibrium orientation, or interface en...
متن کاملSelective ablation of Xe from silicon surfaces: molecular dynamics simulations and experimental laser patterning.
The mechanism of laser-induced removal of Xe overlayers from a Si substrate has been investigated employing MD simulations and evaluated by buffer layer assisted laser patterning experiments. Two distinct regimes of overlayer removal are identified in the simulations of a uniform heating of the Si substrate by a 5 ns laser pulse: The intensive evaporation from the surface of the Xe overlayer an...
متن کاملMagnetic properties of Co/Ag/Co films grown on Ag(100) nanometer-scale islands
Self-assembled Ag(100) islands on Si(100) substrate were fabricated by using the molecular beam epitaxy technique. Co/Ag/Co films were then grown onto Ag films at 100 °C. We have experimentally demonstrated that the magnetic behavior of Co/Ag/Co films is strongly dependent on the thickness and morphology of the Ag(100) islands that serve as a buffer layer. The buffer layer designed to reduce th...
