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 ... -
Wannier-function-based constrained DFT with nonorthogonality-correcting Pulay forces in application to the reorganization effects in graphene-adsorbed pentacene
(2018)Pulay terms arise in the Hellmann-Feynman forces in electronic-structure calculations when one employs a basis set made of localized orbitals that move with their host atoms. If the total energy of the system depends on a ... -
Effect of molecular conformations on the electronic transport in oxygen-substituted alkanethiol molecular junctions
(2018)The relationship between the molecular structure and the electronic transport properties of molecular junctions based on thiol-terminated oligoethers, which are obtained by replacing every third methylene unit in the ... -
Spin injection and magnetoresistance in MoS2-based tunnel junctions using Fe3Si Heusler alloy electrodes
(2018)Recently magnetic tunnel junctions using two-dimensional MoS2 as nonmagnetic spacer have been fabricated, although their magnetoresistance has been reported to be quite low. This may be attributed to the use of permalloy ... -
SQUID-detected FMR: Resonance in single crystalline and polycrystalline yttrium iron garnet
(2018)Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance (FMR)/ferrimagnetic resonance ... -
Ultra-soft magnetic Co-Fe-B-Si-Nb amorphous alloys for high frequency power applications
(2018)With the continuous shrinkage of the footprint of inductors and transformers in modern power supplies, higher flux, while still low-loss metallic replacements of traditional ferrite materials are becoming an intriguing ... -
Bacterially synthesized tellurium nanostructures for broadband ultrafast nonlinear optical applications
(2019)Elementary tellurium is currently of great interest as an element with potential promise in nano-technology applications because of the recent discovery regarding its three two-dimensional phases and the existence of Weyl ... -
Liquid phase exfoliation of MoO<inf>2</inf> nanosheets for lithium ion battery applications
(2019)Molybdenum dioxide (MoO2) is a layered material which shows promise for a number of applications in the electrochemical energy storage arena. Mostly studied as a bulk layered material, MoO2 has not previously been exfoliated ... -
Suppression of the metal-insulator transition in magnetron sputtered Ti2O3 films
(2020)We report on the synthesis of titanium suboxide films using a magnetron sputtering setup. The structure of the produced films is characterized using Raman spectroscopy and X-ray diffraction and electrical properties are ... -
Growth of ZnO:Al by atomic layer deposition: Deconvoluting the contribution of hydrogen interstitials and crystallographic texture on the conductivity
(2019)Aluminium doped ZnO (AZO) is an interesting low cost transparent conducting oxide with further use as an inorganic transport layer in multilayer solar cells. Here we present our work on atomic layer deposited (ALD) thin ... -
Imaging domains in a zero-moment half-metal
(2019)We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromagnets or compensated ferrimagnets, which ... -
Tracking of an electron beam through the solar corona with LOFAR
(2018)The Sun’s activity leads to bursts of radio emission, among other phenomena. An example is type-III radio bursts. They occur frequently and appear as short-lived structures rapidly drifting from high to low frequencies in ... -
LOFAR observations of the quiet solar corona
(2018)Context. The quiet solar corona emits meter-wave thermal bremsstrahlung. Coronal radio emission can only propagate above that radius, Rω, where the local plasma frequency equals the observing frequency. The radio interferometer ... -
Demonstration and interpretation of "scutoid" cells formed in a quasi-2D soap froth
(2018)Recently a novel type of epithelial cell has been discovered and dubbed the ‘scutoid’. It is induced by curvature of the bounding surfaces. We show by simulations and experiments that such cells are to be found in a dry ... -
Properties of lightweight fibrous structures made by a novel foam forming technique
(2019)We describe a novel method for the production of lightweight fibrous structures of densities as low as 8.8 kg m−3 . The method is based on the use of liquid foam as a carrier medium for dispersed Kraft fibres. Different ... -
Enhanced Forster resonance energy transfer between CdTe quantum dots in proximity to gold nanoparticles
(SPIE, 2007)Förster resonant energy transfer (FRET) between the CdTe quantum dot (QD) acting as donors and acceptors is investigated at nanoscale proximity to gold nanoparticles (Au NPs). Photoluminescence (PL) studies of the acceptor ... -
Bending stability of Cu0.4CrO2 - A transparent p-type conducting oxide for large area flexible electronics
(2018)The current best performing p-type transparent conducting oxides are typically highly crystalline materials, deposited at high temperatures, and hence incompatible with the drive to low cost flexible electronics. We ... -
Reflectance anisotropy spectroscopy of Fe3O4(110): Anisotropic strain
(2018)We present a study of (110)-terminated magnetite using a range of surface-sensitive techniques, the foremost of those being reflectance anisotropy spectroscopy (RAS). The anisotropic optical response of the as-polished and ... -
Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet
(2018)The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetization of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically distinct sublattices, such as rare-earth ... -
A photochemical approach for a fast and self-limited covalent modification of surface supported graphene with photoactive dyes.
