摘要: Abstract The effect of hydrogen (H2) gas exposure on the field emission properties tin oxide (SnO2) nanowires films synthesized by carbon thermal reduction vapor transport method was investigated. H2 results in turn-on voltage for driving a current 10 nA from 7.6 V/μm to 5.5 V/μm and increase based 10 V/μm 0.47 μA 2.1 μA. Fowler–Nordheim plot obtained current–voltage data supports that enhancement SNW film is attributed work function exposure.
