Abstract

A probe-hole Field Emission Microscope (FEM) features the capability of measuring the respective dependence of local and total field emission currents on applied voltage.A FEM equipped with a probe-hole

which could be submitted to two-dimensional motion

was employed to acquire curves of field emission current versus applied voltage of single-walled carbon nanotubes (SWCNTs).The field emission currents were acquired from different regions and different adsorption states.Furthermore

the influence of heat treatment on current-voltage behaviors of the SWCNTs was also studied.
