Abstract / Description of output
We have fabricated a new van-der-Waals heterostructure composed by
BN/graphene/C60. We performed transport measurements on the
preliminary BN/graphene device finding a sharp Dirac point at the
neutrality point. After the deposition of a C60 thin film by
thermal evaporation, we have observed a significant n-doping of the
heterostructure. This suggests an unusual electron transfer from
C60 into the BN/graphene structure. This
BN/graphene/C60 heterostructure can be of interest in
photovoltaic applications. It can be used to build devices like p-n
junctions, where C60 can be easily deposited in defined
regions of a graphene junction by the use of a shadow mask. Our results
are contrasted with theoretical calculations.
