WO2 nanowires were grown on Cr/Al electrode on a 0.5 inch glass substrate at low temperature. Field emission properties were measured to investigate their future application in a field emission display devices. The WO2 nanowires are found to have a turn-on field of 9.8 MV/m and their emission current density can reach 1.6 mA/cm2 when the applied field is 14 MV/m. It suggests that they should have...
