Domain wall configuration and magneto-transport properties in dual spin-valve with nanoconstriction
(2012)
We investigated the effect of external field on magneto-transport properties of synthetic antiferromagnet dual spin-valve with nanoconstriction with focus on domain wall (DW) configuration and magnetization reversal process. ...
Effects of excitonic diffusion on stimulated emission in nanocrystalline ZnO
(American Institute of Physics, 2006)
We present optically pumped emission data for ZnO, showing that high excitation effects and
stimulated emission/lasing are observed in nanocrystalline ZnO thin films at room temperature,
although such effects are not ...
Study of shear force as a distance regulation mechanism for scanning near-field optical microscopy
(American Institute of Physics, 1996)
Results of the investigation into the suitability of the shear?force distance regulation mechanism for scanning near?field optical microscopy (SNOM) are presented. It is shown that there is a range of relative sizes of ...
Quantitative comparison of ultracentrifuged and diluted single walled nanotube
(2009)
We have carried out a quantitative comparison of the dispersion quality for ultracentrifuged and diluted surfactant-stabilised single walled nanotube dispersions. We have characterised these dispersions at a set concentration ...
Encapsulation of the heteroepitaxial growth of wide band gap γ-CuCl on silicon substrates
(2006)
γ-CuCl semiconductor material has been identified as a candidate material for the fabrication of blue-UV optoelectronic devices on Si substrates due to its outstanding electronic, lattice and optical properties. However, ...
Ferromagnetism in Fe-doped SnO2 thin films
(American Physical Society, 2004)
Thin films grown by pulsed-laser deposition from targets of Sn0.95Fe0.05O2 are transparent ferromagnets with Curie temperature and spontaneous magnetization of 610 K and 2.2?A?m2?kg?1, respectively. The 57Fe Mossbauer ...
Comment on the giant quadrupole interaction in EuxRhB.
(American Physical Society, 1986)
Controllable broadband nonlinear optical response of graphene dispersions by tuning vacuum pressure.
(2013)
Nonlinear scattering, originating from laser induced solvent micro-bubbles and/or micro-plasmas, is regarded as the principal mechanism for nonlinear optical (NLO) response of graphene dispersions at ns timescale. In this ...
GaN resonant cavity light-emitting diodes for plastic optical fibre applications
(2004)
The optical designs of resonant GaN light-emitting diodes (LEDs) have been determined for maximum extraction efficiency into typical plastic optical fiber of numerical aperture 0.5. An optimum extraction efficiency of 3.9% ...
Incorporating magnetic field observations in wind models of low-mass stars
(2014)
Stellar winds of cool, main-sequence stars are very tenuous and difficult to observe. Despite carrying
away only a small amount of the stellar mass, they are important for regulating the rotation of the star and, ...
