Al-doped ZnO has attracted much attention as a transparent electrode. The graphene-like ZnO monolayer as a two-dimensional nanostructure material shows exceptional properties compared to bulk ZnO. Here, through first-principle calculations, we found that the transparency in the visible light region of Al-doped ZnO monolayer is significantly enhanced compared to the bulk counterpart. In particul...

Preliminary spectroscopy measurements of Al-Al2Ox-Pb tunnel junctions doped with single molecule magnets J. R. Nesbitt Department of Physics, University of Florida Tunnel junctions have been fabricated in which the insulating barrier of Al-Al2OxPb have been doped with single molecule magnets. Low frequency resistance measurements show that the molecules are present in the insulating barrier. Th...

We report growth and characterization of heavily boron-doped 3C-SiC and 6H-SiC and Al-doped 3C-SiC. Both 3C-SiC:B and 6H-SiC:B reveal type-I superconductivity with a critical temperature Tc=1.5 K. On the other hand, Al-doped 3C-SiC (3C-SiC:Al) shows type-II superconductivity with Tc=1.4 K. Both SiC:Al and SiC:B exhibit zero resistivity and diamagnetic susceptibility below Tc with effective hole...

The transmission of transparent colored ceramics based on Al(2)O(3) doped with light transition metals is measured in the visible and infrared range. To clarify the role of the dopands we perform ab initio calculations. We discuss the electronic structure and present optical spectra obtained in the independent particle approximation. We argue that the gross spectral features of Co- and Ni-doped...

Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward (C3H4) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of methylacetylene (C3H4) the pristine nanotubes is a bout -1.78kcal/mol. But when nanotube have been doped with Si and Al atomes, the adsorption energy of me...

This paper describes a preliminary study of the thermoluminescence (TL) response of doped SiO(2) optical fibres subjected to (241)AmBe neutron irradiation. The TL materials, which comprise Al- and Ge-doped silica fibres, were exposed in close contact with the (241)AmBe source to obtain fast neutron interactions through use of measurements obtained with and without a Cd filter (the filter being ...

We investigated whether Aluminum (Al) doping tunes band gap energy level as well as selective cytotoxicity of ZnO nanoparticles in human breast cancer cells (MCF-7). Pure and Al-doped ZnO nanoparticles were prepared by a simple sol-gel method. Characterization study confirmed the formation of single phase of Al(x)Zn(1-x)O nanocrystals with the size range of 33-55 nm. Al-doping increased the ban...

Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward hydroquinone (C6H4(OH)2) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G(d) level, and it was found that the adsorption energy (Ead) of hydroquinone on the pristine nanotube is  a bout -7.77kcal/mol. But when nanotubes have been doped with Si and Al atomes, the adsorption energy of hy...

Undoped and Al-doped ZnO films were synthesized by atomic layer deposition at 150°C and then annealed at 350°C in different atmospheres. Effects of doping and annealing on the film growth mode and properties were investigated. The undoped film has strong UV emission and weak Zn interstitial emission. Annealing introduces O vacancies, decreases Zn interstitials, and results in weakening and blue...

Transparent conducting Al-doped ZnO films were deposited by atomic layer deposition with various of Al doping concentrations. In order to explain the change in resistivity of Al-doped ZnO films depending on Al doping concentration, we investigated the correlations between the conducting property and electronic structure in terms of atomic configuration, the evolution of the conduction band and ...
