Abstract
We have constructed a measurement system for field emission spectroscopy (FES) of cold cathodes. Its commissioning with a tungsten needle yielded an electron energy resolution of less than 50 meV. Combined FES and current-field measurements on column arrays of entangled multiwall carbon nanotubes resulted in a work function of Φ = 4.86 ± 0.4 eV which confirms the literature data.
