  • Synthesis and characterization of single crystalline REBa/sub 2/Cu/sub 3/O/sub 7-y/ thin film grown by tri-phase epitaxy
    IEEE Transactions on Applied Superconductivity, 2003
    Co-Authors: Yuji Matsumoto, M Kawasaki, S. Arisawa, Y. Takano, A. Ishii, T. Hatano, K. Togano, Hideomi Koinuma
    Abstract:

    We report on the successful fabrication of single crystalline thin films of REBa/sub 2/Cu/sub 3/O/sub 7-y/ (RE123, RE: rare earth elements) using a novel process of Tri-Phase Epitaxy. This method is based on the application of pulsed laser deposition (PLD) under appropriate compositions and conditions predetermined from the Relevant Thermodynamic phase diagram. Prior to the growth of the film, a liquid phase film (near-eutectic composition of BaO-CuO) is intentionally formed. The RE123 single crystalline thin film is grown at the liquid-solid interface. The consumed RE123 in the liquid layer is compensated by the laser-ablated vapor and the composition of the liquid phase is kept constant. Thermodynamic equilibrium can be maintained at the liquid-solid film boundary while preserving the benefit of intrinsic stoichiometry control offered by the PLD technique. Atomically smooth film surface and single crystalline nature of film was verified by combined characterization methods of x-ray diffraction, atomic force microscopy and transmission electron microscopy.

  • vapor liquid solid tri phase pulsed laser epitaxy of rba2cu3o7 y single crystal films
    Applied Physics Letters, 2002
    Co-Authors: B D Choi, Yuji Matsumoto, J H Song, Naoki Kanda, Takayuki Itoh, M Kawasaki, Toyohiro Chikyow, P Ahmet, Hideomi Koinuma
    Abstract:

    We report on the fabrication of single-crystalline thin films of RBa2Cu3O7−y (R: rare-earth element, R123) using an approach of vapor–liquid–solid tri-phase epitaxy. This method is based on application of pulsed-laser deposition under appropriate compositions and conditions predetermined from the Relevant Thermodynamic phase diagram. The laser-ablated gases of R, Ba, and Cu, and their oxides dissolve into a liquid Ba3Cu5Ox (3BaCuO2+2CuO) layer placed on the film/substrate surface, penetrate to reach the liquid–solid interface with a seed R123, and are condensed into the solid R123 phase under a quasiequilibrium state. The uniform single-crystalline nature of the film was verified by x-ray diffraction, atomic-force microscopy, and transmission electron microscopy by the observation of giant grain size and atomic-scale surface smoothness.

  • solid state reaction of nickel silicide and germanide contacts to semiconductor nanochannels
    Semiconductor Science and Technology, 2014
    Co-Authors: Wei Tang, Binhminh Nguyen, Renjie Chen, Shadi A Dayeh
    Abstract:

    The surge in advancing the materials science of solid-state reactions for nanoscale contacts to advanced semiconductor devices necessitates a comprehensive dissemination and discussion on recent progress. The objective of this work is to review the notable developments in compound and alloy contact formation to nanoscale nanowire channels made of germanium, silicon, and their heterostructures, and to develop a unifying framework for understanding the significantly distinct reaction behaviors from those commonly observed in bulk. The Ni-based compound and alloy contacts are used as a platform to highlight the size-Relevant, Thermodynamic, and kinetic differences, and their key material, reaction, and electronic parameters and properties are summarized. Special attention is given to the interplay between the compound/alloy contact structure and the resultant electronic properties.
