We report the results on the measurements of the work function of single-walled carbon nanotubes encapsulated by AgI (AgI@SWCNT), AgCl (AgCl@SWCNT), and CuBr (CuBr@SWCNT) by the local Kelvin probe technique. We found the values of the work function of tubes encapsulated with AgI and AgCl (Φ (AgI@SWCNT, Φ (AgCl@SWCNT eV) to exceed substantially that of pristine carbon nanotubes, and the value of the work function of carbon nanotubes encapsulated with CuBr is Φ (CuBr@SWCNT (eV). The measurements are carried out using different kinds of microscope probes including multi-walled carbon nanotube tips.
