Investigation of the Shape of InGaAs/GaAs Quantum Dots

January 1, 2003
Author(s)
Susan Y. Lehman, Alexana Roshko, Richard Mirin, John E. Bonevich
Three samples of self-assembled In 0.44Ga 0.56As quantum dots (QDs) grown on (001) GaAs by molecular beam epitaxy (MBE) were studied using atomic force microscopy (AFM)) and high-resolution transmission electron microscopy (TEM) in order to characterize

Synthesis and Characterization of Colloidal Beta-HgS Quantum Dots

October 1, 2002
Author(s)
K A. Higginson, M Kuno, John E. Bonevich, S B. Qadri, M Yousuf, H Mattoussi
High-quality colloidal mercury sulfide quantum dots (QDs) are synthesized at room temperature using a synthetic strategy combining the effects of strongly binding Hg(II) ligands with a two-phase metal/chalcogen precursor compartmentalization scheme. This

Superconformal Electrodeposition of Silver in Submicrometer Features

August 1, 2002
Author(s)
Thomas P. Moffat, B C. Baker, Daniel Wheeler, John E. Bonevich, Monica D. Edelstein, D R Kelly, L Gan, Gery R. Stafford, P J. Chen, William F. Egelhoff Jr., Daniel Josell
The generality of the curvature enhanced accelerator coverage (CEAC) model of superconformal electrodeposition is demonstrated through application to superconformal filling of fine trenches during silver deposition from selenium-catalyzed silver cyanide

Ferromagnetic Resonance Mode Interactions in Periodically Perturbed Films

May 1, 2002
Author(s)
Robert McMichael, D J. Twisselmann, John E. Bonevich, P J. Chen, William F. Egelhoff Jr., Stephen E. Russek
rromagnetic resonance linewidth measurements are reported for thin films of Ni 80Fe 20 deposited on substrates with 320 nm period grooves or parallel aperiodic scratches. These films are model systems for studying the effects of inhomogeneity on

From Bulk to Nanoscale Magnetism and Exchange Bias in CuO Nanoparticles

November 1, 2001
Author(s)
A Punnoose, H Magnone, M Seehra, John E. Bonevich
Detailed studies of the temperature (5 K to 350 K) and magnetic field variations (up to H = 50 k0e) of the magnetization of CuO nanoprticles of size range 37 nm to 6.6 nm are reported. These particles are synthesized by the sol-gel method in combination

Large Anisotropy Via Oblique Sputtering of Ta Underlayers

May 1, 2001
Author(s)
John E. Bonevich, Robert D. McMichael, Chang H. Lee, P J. Chen, W Wyatt Miller, William F. Egelhoff Jr.
Anisotropy fields in excess of 120 KA/m (1500 Oe) have been produced in 3 nm to 5 nm thick polycrystalline films of Co by oblique sputtering of Ta underlayers. The unusually high anisotropy is magnetostatic in origin, and is induced by corrugations on the

Cu Electrodeposition for On-Chip Interconnections

January 1, 2001
Author(s)
Gery R. Stafford, Thomas P. Moffat, V D. Jovic, David R. Kelley, John E. Bonevich, Daniel Josell, Mark D. Vaudin, N G. Armstrong, W H. Huber, A Stanishevsky
The electrochemical behavior of copper in copper sulfate - sulfuric acid, containing various combinations of NaCl, sodium 3 mercapto-1 propanesulfonate (MPSA), and polyethylene glycol (PEG) is examined. The i-E deposition characteristics of the
