Journal ArticleDOI
Spin-Dependent Tunneling in Self-Assembled Cobalt-Nanocrystal Superlattices
TL;DR: Self-assembled devices composed of periodic arrays of 10-nanometer-diameter cobalt nanocrystals display spin-dependent electron transport and low-energy spin-flip scattering suppresses magnetoresistance with increasing temperature and bias-voltage.
Journal ArticleDOI
Direct observation of electronic anisotropy in single-crystal Y1Ba2Cu3O7-x.
TL;DR: Critical-field and critical-current measurements performed on single crystals show anisotropic electronic behavior of the high-temperature superconductor with anisotropies of 10 and greater.
Journal ArticleDOI
Magnetic, electronic, and structural characterization of nonstoichiometric iron oxides at the nanoscale.
Franz X. Redl,Charles T. Black,Georgia C. Papaefthymiou,Robert L. Sandstrom,Ming Yin,Hao Zeng,Christopher B Murray,Stephen O'Brien +7 more
TL;DR: The complex and metastable behavior of nonstoichiometric iron oxide (wüstite) at the nanoscale was studied by a combination of Mossbauer spectroscopy and magnetic characterization.
Journal ArticleDOI
Nanoscale patterning using self-assembled polymers for semiconductor applications
TL;DR: In this article, the authors investigate the process window for forming ordered arrays of nanoscale polymer domains in thin films across 8-in-diam silicon wafers, including the effect of substrate material and surface treatment, annealing conditions, copolymer molecular weight, and film thickness.
Journal ArticleDOI
Room-temperature ferromagnetic nanotubes controlled by electron or hole doping
Lia Krusin-Elbaum,D.M. Newns,Hao Zeng,Vincent Derycke,Vincent Derycke,Jonathan Z. Sun,Robert L. Sandstrom +6 more
TL;DR: The as-formed nanotubes are transformed from spin-frustrated semiconductors to ferromagnets by doping with either electrons or holes, potentially offering a route to spin control in nanotube-based heterostructures.
