-
(Cambridge University Press, 2016-06)In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, α-Fe2O3 received significant attention as a promising photoanode due to its band gap (∼2.1 eV), good ...
-
(Elsevier, 2016-03)Deep-level transient spectroscopy (DLTS) and Laplace-DLTS were used to investigate the effect of alpha-particle irradiation on the electrical properties of nitrogen-doped 4H-SiC. The samples were bombarded with alpha-particles ...
-
(Elsevier, 2016-01)The defects introduced in epitaxially grown p-type silicon (Si) during electron beam exposure were electrically characterised using deep level transient spectroscopy (DLTS) and high resolution Laplace-DLTS. In this process, ...
-
(World Academy of Science, Engineering and Technology, 2014)A theoretical approach to consider formation of chemical compound layer at the interface between initial substances A and B due to the interfacial interaction and diffusion is developed. It is considered situation when ...
-
(EDP Sciences, 2011-08-11)ZnO nanorods arrays were prepared on soda lime glass substrate by pulsed laser deposition method. Hexagonal rod-like ZnO rods were obtained under different conditions.Well-defined ZnO nanorods arrays were selected among ...
-
(Elsevier, 2016-09)By means of density functional theory (DFT), using the screened Heyd, Scuseria, and Ernzerhof (HSE06) hybrid functional we present results of the Tm3+Ge-VGe defect complexes in germanium (Ge). The formation energies of ...
-
(Elsevier, 2016-01)This paper reports on the deposition of pure and 5 at.% Al doped ZnO (AZO) prepared by sol-gel and applied to the substrates by spin-coating, and the role of annealing temperature on the crystallinity of these layers. It ...
-
(American Physical Society, 2016-03-08)The nuclei that constitute a crystalline lattice, oscillate relative to each other with a very low energy that is not sufficient to penetrate through the Coulomb barriers separating them. An additional energy, which is ...
-
(Royal Society of Chemistry, 2016-05)An asymmetric supercapacitor fabricated with CoAl-layered double hydroxide/graphene foam (LDH/GF) composite as the positive electrode and activated carbon derived from expanded graphite (AEG) as negative electrode in ...
-
(Elsevier, 2016-09)This work present the synthesis and electrochemical performance of mesoporous carbon material derived from the activation and carbonisation of polypyrole (PPY). Electrochemical performance of the PPY derived carbon was ...
-
(World Scientific Publishing, 2016-02)A new parametrization of the multi-channel S S -matrix is used to fit scattering data and then to locate the resonances as its poles. The S S -matrix is written in terms of the corresponding “in” and “out” Jost ...
-
(Elsevier, 2015-07)Pulsed laser deposition technique was used to deposit Cr2O3 nanostructured thin film on a chemical vapour deposited few-layer graphene (FLG) on nickel (Ni) substrate for application as anode material for lithium-ion ...
-
(Elsevier, 2016-10)The green chemistry route (Microwave) has been used to produce nanocomposite materials based on activated carbon (AC) and manganese (Mn) oxide nanostructures. XRD analysis revealed that amorphous and crystalline oxide ...
-
(Royal Society of Chemistry, 2016-04)VS2 nanosheets as the positive electrode and the activated carbon (AC) as the negative electrode with a 6 M KOH solution as electrolyte were fabricated as an asymmetric supercapacitor. These materials were combined to ...
-
(Elsevier, 2016-06)Using both the Perdew–Burke–Ernzerhof (PBE) functional and the hybrid functional of Heyd–Scuseria– Ernzerhof (HSE06), the metastability of the carbon-substitutional–carbon-interstitial (CsCi) defect in silicon has been ...
-
(American Institute of Physics, 2016)Defects induced by electron irradiation in n-GaAs have been studied using deep level transient spectroscopy (DLTS) and Laplace DLTS (L-DLTS). The E0.83 (EL2) is the only defect observed prior to irradiation. Ru/n-GaAs ...
-
(Elsevier, 2016-08)We have studied the defects introduced in n-type 4H-SiC during electron beam deposition (EBD) of tungsten by deep-level transient spectroscopy (DLTS). The results from currentvoltage and capacitance-voltage measurements ...
-
(Springer, 2016-06)Ni(OH)2/graphene foam (GF) electrode was synthesized for electrochemical application by a facile hydrothermal reflux technique. The results obtained from the scanning electron microscopy showed that the Ni(OH)2 spheres ...
-
(Elsevier, 2015-09)A scalable production of high surface area nanoporous carbon material (~ 2994 m2 g-1) with good distribution of micro-, meso- and macro-pores was hydrothermally synthesized using both cheap polymers and graphene foam as ...
-
(Elsevier, 2016-08)We present a stable inkjet printable graphene ink, formulated in isopropyl alcohol via liquid phase exfoliation of chemically pristine graphite with a polymer stabilizer. The rheology and low deposition temperature of ...
