A highly stable field emitter based on thin, quasi-aligned SnO2 nanowire ensembles with uniform diameter is reported. Field-emission measurements of these SnO2 nanowire ensembles showed low turn-on and threshold voltages and very long-term stability of more than 2400 min. The excellent field emission characteristics are mainly attributed to their high crystallinity, high aspect ratio, uniform 1D geometry and diameter distribution, and quasi-aligned growth.
