We present numerical simulations of low aspect ratio gallium phosphide nanowires under plane wave illumination, which reveal the interplay between transverse and longitudinal antenna-like resonances. A comparison to the limiting case of the semiconducting sphere shows a gradual, continuous transition of resonant electric and magnetic spherical Mie modes into Fabry-Pérot cavity modes with mixed ...

Amorphous mixed metal oxides are emerging as high performance semiconductors for thin film transistor (TFT) applications, with indium gallium zinc oxide, InGaZnO (IGZO), being one of the most widely studied and best performing systems. Here, we investigate alkaline earth (barium or strontium) doped InBa(Sr)ZnO as alternative, semiconducting channel layers and compare their performance of the el...

A variety of deposition methods for two-dimensional crystals have been demonstrated; however, their wafer-scale deposition remains a challenge. Here we introduce a technique for depositing and patterning of wafer-scale two-dimensional metal chalcogenide compounds by transforming the native interfacial metal oxide layer of low melting point metal precursors (group III and IV) in liquid form. In ...

We have demonstrated Schottky diodes using semiconducting single-walled nanotubes (s-SWNTs) with titanium Schottky and platinum Ohmic contacts for high-frequency applications. The diodes are fabricated using angled evaporation of dissimilar metal contacts over an s-SWNT. The devices demonstrate rectifying behavior with large reverse bias breakdown voltages of greater than -15 V. To decrease the...

A time domain simulation algorithm for the investigation of propagation properties of nonlinear Surface-PlasmonPolaritons (SPP) mode through gallium lanthanum sulphide (GLS) layer in Ag-GLS-Ag waveguide is presented. GLS, a semiconducting chalcogenide glass is known as ultrafast nonlinear device due to their high material non-linearity with strong confinement and dispersion. The time domain sim...

Gallium nitrate is active against lymphoma and bladder cancer; however, little is understood about tumor resistance to this drug. Transferrin, the iron transport protein, increases gallium uptake by cells, whereas pyridoxal isonicotinoyl hydrazone (PIH), an iron chelator, transports iron into cells. Therefore, we examined whether these metal transporters would increase the cytotoxicity of galli...

Electropolymerization of novel gallium Schiff-base complexes results in conducting metallopolymers containing either coordinatively saturated or unsaturated gallium metal centers. Depending on the chemical coordination of the metal centers, the embedded metal ions can act as seed points for the direct growth of size-controlled gallium sulfide nanoparticles in a conducting polymer, yielding a hy...

Adam J. Hauser and Fengyuan Yang Department of Physics, The Ohio State University, 191 Woodruff Avenue, Columbus, Ohio 43210, USA (Dated: August 22, 2010) Abstract Ferromagnetic δ-phase manganese gallium layers with Mn/(Mn + Ga) = 60% have been successfully grown on ScN(001) by molecular beam epitaxy, expanding possibilities for ferromagnetic layers on nitride semiconductors. The in-plane epita...

Clinical studies have shown gallium nitrate to have significant antitumor activity against non-Hodgkin's lymphoma and bladder cancer, thus indicating that gallium-based drugs have potential for further development as antineoplastic agents. In this study, we compared the cytotoxicity of gallium maltolate, a novel gallium compound, with gallium nitrate in lymphoma cell lines, including p53 varian...
