All-printed dielectric capacitors from high permittivity, liquid-exfoliated BiOCl nanosheets
(2020)Printed networks of insulating 2D materials are promising for dielectric applications in printed electronic devices. However, this work has not really progressed beyond networks of BN nanosheets displaying dielectric ... -
ALMA Observations of Non-uniform Dust Mass-loss in the Inner Circumstellar Environment of the Red Supergiant VY CMa
(2015)The processes leading to dust formation and the subsequent role it plays in driving mass loss in cool evolved stars is an area of intense study. Here we present high resolution ALMA Science Verification data of the continuum ... -
ALMA sub-mm maser and dust distribution of VY Canis Majoris
(2014)Cool, evolved stars have copious, enriched winds. Observations have so far not fully constrained models for the shaping and acceleration of these winds. We need to understand the dynamics better, from the pulsating stellar ... -
Alternating and direct current characterization and photoinduced absorption studies of modified conjugated polymer thin films
(2004)Control of interchain separation enables the optical properties of polymer thin films to be altered. We present a thin film preparation technique that increases the free volume fraction in spin coated polymer thin films ... -
Alternating and direct current characterization and photoinduced absorption studies of modified conjugated polymer thin films
(Journal of Applied Physics, 2004)Control of interchain separation enables the optical properties of polymer thin films to be altered. We present a thin film preparation technique that increases the free volume fraction in spin coated polymer thin films ... -
An alternative fluorine precursor for the synthesis of SnO2:F by spray pyrolysis
(2012)An alternative, non-toxic precursor was employed for the synthesis of SnO2:F transparent conducting oxide. The performance of benzenesulfonyl fluoride (BSF) as F source for spray pyrolysis was investigated. Its decomposition ... -
Aluminium doped Zn1−xMgxO A transparent conducting oxide with tunable optical and electrical properties
(2012)A ternary mixed oxide Zn1 xMgxO has been doped with aluminium to create a range of transparent conducting oxides with tunable refractive index as well as work function. Conductive material was synthesised up to a magnesium ... -
Amorphous 2D-Nanoplatelets of Red Phosphorus Obtained by Liquid-Phase Exfoliation Yield High Areal Capacity Na-Ion Battery Anodes
(2023)The development of sodium ion batteries will require high-performance elec-trodes with very large areal capacity and reasonable rate performance. Although red phosphorus is a very promising electrode material, it has not ... -
Amplified spontaneous emission and optical gain spectra from stilbenoid and phenylene vinylene derivative model compounds
(1999)We report single-pass optical gain measurement in polystyrene! waveguides doped with stilbenoid and phenylene vinylene derivative model compounds under picosecond excitation. Using a wavelength dependent model of amplified ... -
Amplified spontaneous emission from a microtube cavity with whispering gallery modes
(2007)We present a detailed study of the photonic modes in microtube cavity of ~ 7-8 ?m outer diameter that can act as micron-scale optical cylindrical resonator. We demonstrate a new route to the fabrication of individual ... -
Amplitude coda of classical waves in disordered media
(2002)The propagation of classical waves in the presence of a disordered medium is studied. We consider wave pulses containing a broad range of frequencies in terms of the configurationally averaged Green function of the system. ... -
Amplitude-mode dynamics of polariton condensates
(2011)We study the stability of collective amplitude excitations in nonequilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collective amplitude modes of atomic gases and ... -
Analysis of liquid metal foams through X-ray radioscopy and microgravity experiments
(2014)Complex liquid structures such as metallic foams were produced in a furnace that allowed in situ X-ray monitoring of the evolution of the structure and distribution of the liquid in the foam. The experiments were carried ... -
Analysis of slot characteristics in single mode semiconductor lasers using the 2D scattering matrix method
(IEEE, 2006)We use the two-dimensional (2-D) scattering matrix method (SMM) to analyze the slot characteristics in slotted single-mode semiconductor lasers and compare the results with those calculated by the one-dimensional transfer ... -
Analysis of the conditional mutual information in ballistic and diffusive non-equilibrium steady-states
(2020)The conditional mutual information (CMI) ℐ(A:C|B) quantifies the amount of correlations shared between A and C given B. It therefore functions as a more general quantifier of bipartite correlations in multipartite scenarios, ... -
Analysis of the foam-forming of non-woven lightweight fibrous materials using X-ray tomography
(2021)Foam-forming has in the past predominantly been used to create two-dimensional sheet-like fibrous materials. Allowing the foam to drain freely and decay under gravity, rather than applying a vacuum to remove it rapidly, ...
