Abstract
Using DFT-based calculations, we study chemical doping of silicene–graphene hybrid with (B, N, Al and P). Planar structure of SiC sheet remains unaffected on doping and all the systems are stable. P and N dopants are strongly bonded to the hybrid compared with Al and N. Charge transfer calculations show that (B, N)/(Al, P) behave like acceptors/donors, respectively. All configurations retain the semi-conductor character of pure SiC and show magnetic order. Curie temperature is determined for the ferromagnetic structures. These results provide the possibility of tuning the gap and inducing magnetism in SiC as required for future applications.
