A scalable and versatile method for the large-scale synthesis of tungsten trioxide nanowires and their arrays on a variety of substrates, including amorphous quartz and fluorinated tin oxide, is reported. The synthesis involves the chemical-vapor transport of metal oxide vapor-phase species using air or oxygen flow over hot filaments onto substrates kept at(More)
Here, we present the results of the resistive response of tungsten trioxide nanowire (mat-like, nanowire networks) and nanoparticle thin films subjected to N 2 O gas in the temperature range of 373–773 K. The nanowire mats exhibited an order of magnitude higher response in the resistivity change compared to that of nanoparticle films at temperatures above(More)
