Piezoelectric Phenomenon of Fullerene-Graphene Bonded Structure
Figure 3
DOS of C60-graphene bonded structure with the strains applied along the fullerene-graphene direction. The value of the strain was labeled and the different colors showed the DOS under different strains, namely, black for no strain, red for the strain of 7%, green for the strain of 13%, blue for the strain of 20%, light blue for the strain of 27%, and purple for the strain of 33%. The local density of states (LDOS) according to the strains of 7%, 13%, and 20% were shown as an inset to show the transition between the semiconductor and the conductor.
