Few layer graphene (FLG) was synthesized by -wave assisted exfoliation of expanded
graphite in toluene with an overall yield from c.a. 7% to 20%. A significant difference in the absorption
of -waves by the expanded graphite and toluene allowed a rapid heating of the medium. The
number of FLG sheets varies from 3 to 12, while the lateral size of the sheets exceeds few ms. The
obtained FLG exhibits very low resistance with average value of 1.6 k (500 minimum) which is
comparable to that of high quality graphenes synthesized by CVD methods, and lower than numbers of
