ABSTRACT
We report on the fabrication of Co 3.4 at. % doped TiO2 nanowire-based field-effect transistors with a back gate of heavily doped Si substrate and their electric field-effect functions. The TiO2:Co nanowire, which was fabricated utilizing a conventional magnetron sputtering technique on a suspended molecular template between electrodes, is a polycrystalline and consists of a chain of nanoparticles on a molecular template. The N-type field-effect transistors prepared from the suspended Co–TiO2 nanowire junction were exhibited on currents, transconductances, and a mobility of up to 0.1 mA/μm, 0.2 μA/V, and μe≈66 cm2/V s, respectively, at room temperature. The unique structure of these inorganic-organic functional devices may enable the fabrication of flexible nanoelectrospin devices.

    Field effect transistors based on a GaN/AlGaN system have shown remarkable performance characteristics in a wide range of device applications. However, due to the large effective mass of GaN, the mobility in the channel is small. In this work, we consider a GaN/AlGaN structure with a thin InN...
