Enhancement of the ozone-sensing properties of ZnO through chemical-etched surface texturing Abstract: Semiconductor metal oxides (SMOx) are widely studied for different applications. It is well established that the gas-SMOx interaction strongly depends on the charge […]
Photocurrent enhancement and magnetoresistance in indium phosphide single nanowire by zinc doping Abstract: We report the fabrication of intrinsic and Zn-doped InP single nanowire devices by the vapor-liquid-solid and photolithography techniques. Nanowires with a zincblend structure […]
Schottky contacts in germanium nanowire network devices synthesized from nickel seeds Abstract: This paper presents reliable process to the synthesis of germanium nanowires by the vapor-liquid-solid method using nickel as an alternative catalyst to gold, […]
One-step preparation of the BiVO4 film photoelectrode Abstract: A one-step method of preparing photoelectrochemically active nanostructured BiVO4 films is reported based on thermolysis (500 A degrees C in air) of a polyethylene glycol (PEG300) “paint-on” precursor […]
Local structure and photoluminescence properties of nanostructured Zn1-xMnxS material Abstract: Zinc sulfide (ZnS) pure or doped has received remarkable attention because of fundamental properties, versatility and potential for several technological applications as luminescent material. In this […]
Ozone gas sensor based on nanocrystalline SrTi1-xFexO3 thin films Abstract: We report on the use of nanocrystalline SrTi1−xFexO3 (STF) for sensing ozone gas. Amorphous thin films were evaporated by the electron-beam physical vapor deposition technique and then converted to a polycrystalline form, as […]
High-performance and low-voltage SnO2-based varistors Abstract: This paper presents the results of a thorough study conducted on the action mechanism of one-dimensional single-crystalline SnO2 nanobelts in decreasing the breakdown electric field (Eb) in SnO2-based varistors. The […]
