DOPED GRAPHENE. “Most of these graphene-silicon prototypes were demonstrated with CVD graphene grown on metal substrates. Development of manipulation processes or technologies to delaminate graphene from its “parenting” substrate and attach to silicon microchips is of paramount demand. It is worth noting that fine tuning of graphene manipulation processes is expected to cater for each application.”
