Abstract :
This study investigates quantum mechanically the effect of spacing of aligned carbon nanotubes on field emission properties. It is known that for a given length of CNTs, it is beneficial for electron emission as the spacing of CNTs are increased. As the spacing of CNTs reduces, the effect of screening becomes stronger and current density become smaller. It is very useful to know the relationship between current density and the spacing of CNTs quantitatively
