(Elsevier, 2014-05)This paper reports on a new technique for sensing the Hall effect in an integrated CMOS device. Contrary totraditional Hall plates where sensor contacts comprise of highly doped, low ohmic contacts, the proposedsensor makes ...
-
(Asian Journal of Chemistry, 2013)Energy dispersive X-ray fluorescence technique was used to study the elemental composition of some historical paper samples obtained from the National Library of South Africa. Six elements namely Fe, Cu, Mn, Ca, K and S ...
-
(Elsevier, 2014-04)Inductively coupled plasma (ICP) etching of germanium introduces a single defect, the E0.31 electron trap, for a large range of argon partial pressures from 4 × 10-3 to 6.5 × 10-4mbar that correspond to ion energies of 8 ...
-
(Elsevier, 2014-04)Primary defects were introduced into n-type gallium nitride (GaN) thin films by 1.6 MeV-proton bombardment at 20 K. The electronic states of these defects were investigated by means of optical space charge spectroscopy. ...
-
(Wiley-Blackwell, 2013)The influence of irradiation induced damage on the transport of implanted species in poly and single crystalline silicon carbide is investigated. For this purpose published diffusion results of strontium, silver, iodine and ...
-
(Elsevier, 2014-08)Solid state reactions between a thin film (133 nm) of Zr and bulk single crystalline 6H-SiC substrates have been studied at temperatures between 600 °C and 850 °C for durations of 30, 60 and 120 min under high vacuum ...
-
(Elsevier, 2014-08)Diffusion of xenon in poly and single crystalline silicon carbide and the possible influence of radiation damage on it are investigated. For this purpose 360 keV xenon ions were implanted in commercial 6H-SiC and CVD-SiC ...
-
(Elsevier, 2014-01)FTIR (Fourier transform infrared) spectroscopy is a non-destructive analytical method that has been used successfully to analyse both inorganic and organic archaeological material. Using a microscope attachment has the ...
-
(Elsevier, 2013)Using theoretical quantum chemical methods, we investigate the dearth of ordered alloys involving thorium and titanium. Whereas both these elements are known to alloy very readily with various other elements, for example ...
-
(Elsevier, 2014-07)The ability to dissipate large fractions of their absorbed light energy as heat is a vital photoprotective function of the peripheral light-harvesting pigment–protein complexes in photosystemII of plants. The major component ...
-
(Wiley-Blackwell, 2014-01)Please read abstract in the article.
-
(Elsevier, 2014)We report on the crystal structure and morphology of vanadium dioxide (VO2) nanostructures synthesized by pulsed laser deposition on soda-lime glass substrates. The VO2 nanostructures exhibit sharp a-axis diffraction ...
-
(Elsevier, 2013)We present a detailed comparative study of the electronic and mechanical properties of the early actinide mononitrides and dinitrides within the framework of the Perdew–Burke–Ernzerhof generalized gradient approximation ...
-
(Elsevier, 2014-01)We herein report a modified, in situ photolytic process for the nucleation and growth of cadmium sulphide nanoparticles in the presence of an optically transparent and semicrystalline polyvinyl alcohol (PVA) polymer ...
-
(Institute of Physics, 2014-01)We study noncommutative Ricci flow in a finite-dimensional representation of a noncommutative torus. It is shown that the flow exists and converges to the flat metric. We also consider the evolution of entropy and a ...
-
(American Institute of Physics, 2013-11)We present a simple and very convincing approach to visualizing that subsequent layers of graphene grow between the existing monolayer graphene and the copper catalyst in chemical vapor deposition (CVD). Graphene samples ...
-
(IOP Publishing Limited, 2013-11-21)We have devised a general numerical scheme applied to a system of independent, distinguishable, non-interacting particles, to demonstrate in a direct manner the extensive nature of statistical entropy. Working within the ...
-
(IOP Publishing Limited, 2013-11-21)Most modern scientific research problems are complex and interdisciplinary in nature. It is impossible to study such problems in detail without the use of computation in addition to theory and experiment. Although it is ...
-
(AOSIS Open Journals, 2013)Entanglement criteria for general (pure or mixed) states of systems consisting of N identical fermions are introduced. These criteria are based on appropriate inequalities involving the entropy of the global density ...
-
(Elsevier, 2014-01)Silver metal nanoparticles were decorated by electron beam evaporation on graphene foam (GF) grown by chemical vapour deposition. X-ray diffraction, Raman spectroscopy, scanning and transmission electron microscopy, and ...
