摘要
Quasi-aligned molybdenum oxide nanowires are synthesized on silicon substrate by a thermal evaporation method, at a low temperature of 550 degrees C without using any catalyst. The diameter of these nanowires is about 100 nm, with steps in the top to form a sharp tip. The field emission measurement shows that these nanowires have strong electron field emission abilities, with high field enhancement factor and a relatively low turn-on field of 2.16 V mu m(-1), suggesting that these molybdenum oxide nanowire arrays might be promising candidates as field emitters.
