Biaxial strain-induced transport property changes in atomically tailored SrTiO3 -based systems
(2014)Several metallic SrTiO3-based systems, including reduced SrTiO3−δ, Nb-doped SrTiO3, and two-dimensional electron gas at the LaAlO3/SrTiO3(001) interface, have been epitaxially fabricated on various substrates inducing ... -
Effect of Catalyst Diameter on Vapour-Liquid-Solid Growth of GaAs Nanowires
(2014)GaAs nanowires were grown on (111)B GaAs substrates using the vapour-liquid-solid mechanism. The Au/Pt nanodots used to catalyse wire growth were defined lithographically and had varying diameter and separation. An in-depth ... -
Hysteresis Magnetoresistance and Micromagnetic Modeling of Ni Microbelts
(2010)Magnetization reversal process in a single nickel microbelt is investigated by measuring magnetoresistance (MR). A hysteresis MR curve is observed, which consists of a reversible bell-shaped curve under high magnetic field ... -
Liquid Exfoliation of Layered Materials
(2013)Not all crystals form atomic bonds in three dimensions. Layered crystals, for instance, are those that form strong chemical bonds in-plane but display weak out-of-plane bonding. This allows them to be exfoliated into ... -
Mn2Au: body centered tetragonal bimetallic antiferromagnet grown by molecular beam epitaxy
(2012): Mn2Au, a layered bimetal, has been successfully grown using MBE technique in AFM/FM bilayer setting. Our experiments and first principle calculations suggest that Mn2Au film is an antiferromagnet with a much lower critical ... -
Thermoelectric behavior of organic thin film nanocomposites
(2013)Organic thin film nanocomposites, prepared by liquid-phase exfoliation, were investigated for their superior electrical properties and thermoelectric behavior. Single-walled carbon nanotubes (SWNT) were stabilized by ... -
Tunneling processes in asymmetric double barrier magnetic tunnel junctions with a thin top MgO layer
(2013)Dynamic conductance dI/dV and inelastic electron tunneling spectroscopy (IETS) d 2I/dV 2 have been measured at different temperatures for double barrier magnetic tunnel junctions with a thin top MgO layer. The resistance ...
