title = "Saturation of emission current from carbon nanotube field emission array",
abstract = "Field emission properties of carbon nanotube field emission arrays (CNT-FEA) that are exposed to various gases were studied. The existence of the hysteresis loop during the rise and fall bias sweep stems from gas adsorbates. We observed that gas adsorbates played an important role in the formation of current saturation at high field region oxygen and nitrogen gases show different trends in the variation of the emission properties from hydrogen gases. The changes of the slopes, turn-on voltages, and current saturation are strongly correlated to the electronegativity of the individual species and the nature of adsorption. Oxygen gas dominates the filed emission properties upon adsorption and even degrades the surface morphologies with possible oxidative etching process, whereas hydrogen gases give the least effect to the field emission properties and additionally enhance the emission current by cleaning the surface of the carbon nanotube array.",
