Interface engineering of graphene nanosheet reinforced ZrB2 composites by tuning surface contacts
(American Physical Society (APS), 2019)The mechanical properties of heterophase interfaces are critically important for the behavior of graphenereinforced composites. In this work, the structure, adhesion, cleavage, and sliding of heterophase interfaces formed ... -
Interfacial transport properties between a strongly correlated transition metal oxide and a metal: Contact resistance in Fe3O4/M (M=Cu, Au, Pt) nanostructures
(2010)Multiterminal measurements have typically been employed to examine electronic properties of strongly correlated electronic materials such as transition metal oxides without the influence of contact effects. In contrast, ... -
Interfacing 2D VS2 with Janus MoSSe: Antiferromagnetic electric polarization and charge transfer driven Half-metallicity
(2021)Half metallic 2D materials with 100% spin polarization at the fermi level can be applied to spintronics to enhance the device efficiency. We identified that the Janus MoSSe monolayer can induce halfmetallicity in the VS2 ... -
Interferometer based in-band OSNR monitoring of single and dual polarisation QPSK signals
(IEEE Computer Society, 2010)The in-band OSNR of SP and DP QPSK signals were measured over a range of 10 to 21dB ?1dB using a pair of polarisation independent Michelson fibre interferometers without the requirement for prior knowledge of the signal's ... -
Interlayer dielectric function of a type-II van der Waals semiconductor: The HfS2/PtS2 heterobilayer
(American Physical Society (APS), 2019)Heterogeneous stacks of two-dimensional transition-metal dichalcogenides can be arranged so as to have a type-II band alignment, where the valence band maximum and the conduction band minimum are located on different layers. ... -
Internalization of ferromagnetic nanowires by different living cells
(2006)The ability of living cells, either adherent or suspended, to internalize nickel nanowires is demonstrated for MC3T3-E1, UMR106-tumour and Marrow-Stromal cells. Nanowires were produced by electrodeposition, 20 mum long and ... -
Interplay of bulk and interface effects in the electric-field-driven transition in magnetite
(2010)Contact effects in devices incorporating strongly correlated electronic materials are comparatively unexplored. We have investigated the electrically driven phase transition in magnetite 100 thin films by fourterminal methods. ... -
Intrinsic decoherence mechanisms in the microcavity polariton condensate
(American Physical Society, 2008)The fundamental mechanisms which control the phase coherence of the polariton Bose-Einstein condensate (BEC) are determined. It is shown that the combination of number fluctuations and interactions leads to decoherence ... -
Inverted magnetoresistance in dual spin valve structures with a synthetic antiferromagnetic free layer
(2009)We report an oscillation of the giant magnetoresistance GMR ratio as a function of Ru layer thickness in the CoFe/Cu/ CoFe/Ru/CoFe SAF/Cu/CoFe/IrMn dual spin valve SV structure. A normal GMR with a positive sign is ... -
Investigating the driving mechanisms of coronal mass ejections
(ESO, 2010)Aims. The objective of this study was to examine the kinematics of coronal mass ejections (CMEs) using EUV and coronagraph images, and to make a quantitative comparison with a number of theoretical models. One particular ... -
Investigation of different synthetic routes to and structure-property relationships of poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene)
(2003)The synthesis of poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene) by Horner?Emmons and Wittig condensation polymerisation in three different solvents is described. The chemical and optical properties of the ... -
Investigation of optimum wavelength converter based on nonlinear polarization rotation in a bulk SOA
(2007)This work is focused on understanding and optimising the physical mechanisms responsible for wavelength conversion based on cross-polarisation modulation (XPolM) in a bulk semiconductor optical amplifier. A comparison is ... -
Investigation of polarization dependent gain in a bulk SOA
(2007)The polarization dependence of the gain dynamics in a bulk semiconductor optical amplifier is examined using two experimental setups. The first experimental investigation is based on four-wave mixing. Using a low-pass ... -
Investigation of the physical mechanisms of shear-force imaging
(American Institute of Physics, 1996)It is shown that shear-force imaging, as is commonly used for distance regulation in scanning near-field optical microscopy, is not a reliable technique for accurate topographic measurements. This is because different ... -
Investigation on the origin of the magnetic moment of BiFeO3 thin films by advanced x-ray characterizations
(2006)Single phase 001 -oriented BiFeO 3 BFO thin films grown by pulsed laser deposition can only be obtained in a narrow window of deposition pressure and temperature and have a low magnetic moment. Out of ... -
IrMn as exchange-biasing material in systems with perpendicular magnetic anisotropy
(American Institute of Physics, 2005)Contact between a Co/Pt multilayer and an IrMn film leads to perpendicular exchange bias. The exchange bias field does not depend on the degree of (111) film texture and for Co/Pt multilayers with IrMn at the bottom it can ... -
Is the activity level of HD80606 influenced by its eccentric planet?
(2016)Aims. Several studies suggest that the activity level of a planet-host star can be influenced by the presence of a close-by orbiting planet. Moreover, the interaction mechanisms that have been proposed, magnetic interaction ...
