Influence of Hydrogen Absorbtion on the Emission Properties of Carbon Nanotubes

We present the results of experimental studies of the effect of hydrogen absorption on the emission properties of a charge source based on carbon nanotubes. It is determined that the emission properties of the source improve considerably after exposure in hydrogen atmosphere at pressure of 100 atm and temperature of 300°С for 2 hours: at voltage of 300 V the current of negative charges increases by 10 4 times.
