چکیده

Well-defined monohydride-terminated n-Si(111) electrodes were used to study electrodeposition of Pb and Cu as well as electroless Au deposition on these surfaces. With classical electrochemical methods, in-situ STM, ex-situ AFM, SEM and in-situ SXRD, the initial stages of metal deposition and the epitaxial properties of the metal deposit were investigated. © 2000 Elsevier Science Ltd.

Electrochemical Deposition of Flower-Like Nickel Nanostructures on Well-Defined n-Si (111):H

In this paper the electrodeposition of nickel on n-Si(111):H substrate, in the presence of sulphuric acid, was studied. Cyclic voltammetry has been used to characterize the electrochemical behavior of the system. The nickel deposits had a flower-like morphology with the sphericalnanostructure nucleus, distributed uniformly on the surfaces of the prepared n-Si(111) substrate.

Behavior of Electrodeposited Cd and Pb Schottky Junctions on CH3-Terminated n-Si(111) Surfaces

n-Si/Cd and n-Si/Pb Schottky junctions have been prepared by electrodeposition of Cd or Pb from acidic aqueous solutions onto H-terminated and CH3-terminated n-type Si 111 surfaces. For both nondegenerately nand degenerately n+doped H–Si 111 electrodes, Cd and Pb were readily electroplated and oxidatively stripped, consistent with a small barrier height b at the Si/solution and the Si/metal jun...

Use of Mixed CH3-/HC(O)CH2CH2-Si(111) Functionality to Control Interfacial Chemical and Electronic Properties During the Atomic-Layer Deposition of Ultrathin Oxides on Si(111).

Silicon surfaces terminated with a mixed monolayer containing both a propyl aldehyde functionality and methyl groups were prepared and used to control the interfacial chemical and electronic properties of Si(111) surfaces during atomic-layer deposition (ALD) of Al2O3 or MnO. Si(111) surfaces functionalized only with the aldehyde moiety exhibited surface recombination velocities, S, of 2500 ± 60...

Photooxidation of Halides and Water on n-Silicon Protected with Silicide Layers

The electrochemical and photoelectrochemical behavior of n-type silicon electrodes coated with noble metal silicides and RuO, in aqueous solutions containing various redox couples was investigated. Iridium silicide coated n-Si electrodes, n-Si( Ir), and Ru02-modified n-Si(1r) electrodes can photogenerate 12, Brz, and C12 with high stability and efficiencies (>5%) . The photooxidation of water o...

Detection of Lead and Copper with Nitrogen Doped Diamond-like Carbon Thin Films

Nitrogen doped diamond-like carbon (N-DLC) thin films were prepared on n-Si substrates using a filtered cathodic vacuum arc deposition method. Square wave anodic stripping voltammetry (SWASV) was used to trace Pb and Cu in a neutral KCl solution with pH 7. Stripping voltammograms of Pb and Cu were analyzed in terms of metal concentration, deposition time and deposition potential. The SWASV resu...
