Rajarshi Banerjee,Pushan Ayyub,Gregory B. Thompson,Ramesh Chandra,Praveen Taneja,Hamish L. Fraser +5 more
TL;DR: In this paper, the microstructure, phase stability, magnetic, transport and optical properties of Ni-25 at.%Al alloy thin films, which were deposited from a target of the intermetallic compound Ni3Al onto the oxidized Si substrates at two different temperatures: 45 and 400 °C.
Journal ArticleDOI
Limiting long-range-ordered solids to finite sizes in condensed-matter physics
TL;DR: In this article, the consequences of finite size effects in solids which exhibit cooperative behavior are examined and the underlying principles essential at a microscopic level for each of the three phenomena are elucidated.
Journal ArticleDOI
Non-linear field emission characteristics of copper oxide nanorod mesh: Geometrical interpretation of a structurally heterogeneous emitter
TL;DR: In this paper, the authors consider a random mesh of Cu2O nanorods as a model system, and investigate the field emission from the sidewalls of this multi-layered nano-mesh.
Journal ArticleDOI
Suppression of superconductivity in submicron La1.85Sr0.15CuO4−δ
TL;DR: In this article, it was shown that bulk La1.85Sr0.15CuO4−δ (LSCO) superconducts below 36K. But microcrystalline LSCO with mean particle size ≤700nm (prepared by rapid liquid dehydration) is not superconducting down to 4.2K.
Journal ArticleDOI
Growth of aligned ZnO nanorod arrays from an aqueous solution: effect of additives and substrates.
TL;DR: It is found that seeding the substrate and selecting the appropriate capping agent play the most crucial roles in the alignment of nanorod arrays and should lead to an enhanced understanding of the controllable growth of ZnO crystals and nanostructures.
