The charge storage capacity, quantum capacitance, and atomic structures of transition-metal doped graphene-like/graphene heterostructures were studied by density functional theory (DFT). The impact of transition-metal (TM) doping (Ni, Co, Fe, Mn, Cr, V, Ti, and Sc) on the capacitance capacity of sil...
