21. Compositional Control in Electrodeposited Ni (subscript x) Pt (subscript 1-x) Films
Published: 10/29/2007
Authors: J Mallett, Erik B. Svedberg, John E Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P Moffat
Abstract: Electrochemical co-deposition of a series of fcc Ni(subscript x)PT(subscript 1-x) alloys is demonstrated. The alloy composition is a monotonic function of potential. The Pt-rich Ni(subscript x)PT(subscript 1-x) alloys are formed at potentials posit ...

22. Electrodeposition of Ni in Sub-Micrometer Trenches
Published: 7/2/2007
Authors: S D Kim, John E Bonevich, Daniel Josell, Thomas P Moffat
Abstract: A survey of the effect of cationic, anionic and non-ionic surfactants on the rate and morphological evolution of nickel electrodeposition from a Watts-type bath is presented. Particular attention is given to the prospect for void free filling of sub ...

23. Precise Manipulation and Alignment of Single Nanowire
Published: 3/2/2007
Authors: Qiliang Li, Sang-Mo Koo, Curt A Richter, Monica D Edelstein, John E Bonevich, Joseph J Kopanski, John S Suehle, Eric M. Vogel
Abstract: Nanowires and nanotubes are being intensively investigated for nanoelectronic transport applications. The integration of such nanostructures into circuitry requires a simple, high-efficiency and low-cost strategy. Here we develop a single nanowire ma ...

24. Precise Alignment of single Nanowires and Fabrication of Nanoelectromechanical Switch and Other Test Structures
Published: 3/1/2007
Authors: Qiliang Li, Sang-Mo Koo, Curt A Richter, Monica D Edelstein, John E Bonevich, Joseph J Kopanski, John S Suehle, Eric M. Vogel
Abstract: The integration of nanowires and nanotubes into electrical test structures to investigate their nanoelectronic transport properties is a significant challenge. Here we present a single nanowire manipulating system to precisely manipulate and align in ...

25. Electrodeposition of Cu on Ru Barrier Layers for Damascene Processing
Published: 12/2/2005
Authors: Thomas P Moffat, Marlon L Walker, P J Chen, John E Bonevich, William F. Egelhoff Jr., Lee J Richter, Daniel Josell, C A Witt, T Aaltonen, M Ritala, M Leskela
Abstract: Superfilling of sub-micrometer trenches by direct copper electrodeposition onto PVD and ALD Ru barriers is demonstrated. The Cu nucleation and growth mode is found to be sensitive to the oxidation state of the Ru surface as well as the copper deposi ...

26. Fabrication and Measurement of Tall Stacked Arrays of SNS Josephson Junctions
Published: 6/1/2005
Authors: Nicolas Hadacek, Paul David Dresselhaus, Yonuk Chong, Samuel Paul Benz, John E Bonevich
Abstract: We have made tall, uniform stacked Josephson junction arrays by developing an etch process using an inductively coupled plasma etcher. This process produces vertical profiles in thin-film multilayers of alternating superconducting and normal metals. ...

27. Interparticle Interaction Effects in the Magnetic Properities NiO Nanorods
Published: 5/1/2005
Authors: M Seehra, H Shim, P Dutta, A Manivannan, John E Bonevich
Abstract: Magnetic properties of sol-gel synthesized 5 nm nanorods of NiO, with and without oleic acid coating to affect interparticle interactions, are reported. Particle morphologies were studied by transmission electron microscopy and temperature variations ...

28. Origin of Exchange Decoupling Effects in High-Coercivity Air-Annealed CoPd Multilayers
Published: 5/1/2005
Authors: William F. Egelhoff Jr., Robert D McMichael, J Mallett, Alexander J. Shapiro, Cedric John Powell, John E Bonevich, J H Judy, J H Thomas, Erik B. Svedberg
Abstract: We have achieved excellent exchange decoupling of grains in CoPd multilayers by annealing in air at 300 C. Samples exhibit a slope in the hysteresis loop close to 1.0, nucleation fields as large as 1.1 T, and coercivities as large as 1.6 T. These are ...

29. A Bayesian/Maximum Entropy Method for the Certification of a Nanocrystallite-Size NIST Standard Reference Material
Published: 7/1/2004
Authors: N G Armstrong, W Kalceff, James P Cline, John E Bonevich
Abstract: A Bayesian/Maximum Entropy (MaxEnt) method for determining crystallite size distribution and morphology from size-broadened x-ray line profiles is presented. This method will be used in certifying a nanocrystallite-size standard reference material ( ...
