• Coulomb explosion of graphene with different sizes and layers is investigated via molecular dynamics simulation. A group of collimated ions with average energy of keV can be obtained from the Coulomb explosion process of nanometer-scale multilayer graphene in a tube with nanometer-scale length, as the carbon ion taking on only 1+ charge. The average ion energy is found to be proportional to the square root of the number of atoms in a single layer while also proportional to layer numbers. According to this linear relationship, we estimate that collimated ions with average energy as high as MeV can be generated from graphene layers of several microns while the carbon ions taking on 3+ charge.
