Optical forces exerted on the nanoparticle with the variation of parameters.
(a)Variation of the Fermi energy of graphene. The diameter of the nanoparticle is 10 nm and its refractive index is n = 2. (b) Variation of the nanoparticle’s refractive index. The diameter of the nanoparticle is 10 nm and the Fermi energy is EF = 0.6 eV. (c)Variation of the particle size. The refractive index of nanoparticle is n = 1.5 and the distance between the bottom of the particle and the graphene film is fixed to s = 5 nm as shown in the inset. Other parameters are the same as in Fig. 2.
