Structural, optical and light detection properties on carbon-nanotube-modified ZnO thin films grown at various temperatures from room to 1173 K are investigated. The optical band gap values calculated from reflectivity data show a hump at a critical

We demonstrate how to establish reliable contacts to SnO2 nano-wires by growing these nano-wire on-chip on gold contacts deposited on alumina. The sensor device is used to sense the concentrations of acetone and ethanol in air and their reaction kine
