Abstract: Method to prepare suspended multilayer graphene (MLG) flakes and to form highly conductive (contact resistivity of similar to 0.1 k Omega mu m(2)) and tight mechanical connection between MLG and metal electrodes is described. MLG flakes prepared from natural graphite were precisely deposited over tungsten electrodes using dielectrophoresis, followed by high-temperature thermal annealing in high-vacuum. Considerable strain induced in the suspended part of flakes was revealed by Raman imaging. (C) 2010 American Institute of Physics. [doi:10.1063/1.3528354]
