Study of Kelvin Probe Force Microscopy (KPFM) image and contact potential difference (CPD) profiles of the samples. Height profiles as (a,e,i); potential energy mappings as (b,f,j); superimposed topography for heights and CPD as (c,g,k) and superimposed curves for heights profiles and CPD as (d,h,l) are presented for GG@CH2Cl2, GG@CHCl3 and GG@CCl4, respectively.
