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 $)=5.08\pm 0.02$ , Φ (AgCl@SWCNT $)= 5.10 \pm 0.02$ 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 $)= 4.89 \pm 0.03$ (eV). The measurements are carried out using different kinds of microscope probes including multi-walled carbon nanotube tips.
