Tungsten Oxide Nanowires Grown on Carbon Cloth as a Flexible Cold Cathode
Single crystalline tungsten oxide nanowires (TONWs) have been synthesized on highly flexible, highly conductive, and highly robust carbon cloth by a catalyst-free thermal evaporation method. Field emission with a low threshold field of similar to 4.30 MV m(-1) was observed from the TONWs. This finding opens up opportunities to make light-weight and rollable field-emission displays.
