Field emission of carbon nanotube in different gases (for example, Air, He, Ne) under atmospheric pressure has been studied. The distance between anode and cathode was 100—200 nm. Detailed comparison has been made to characterize the field emission currents and fluctuations in various gases with different anode-cathode distances.
