The field of optomechanics studies the interaction between electromagnetic radiation and mechanical motion mediated by radiation pressure. By using 2-dimensional Materials like graphene or monolayer molybdenum disulfide (MoS2) as ultralight mechanical resonators, large zero point motion can be achieved. This also, simultaneously opens up new possibilities for realizing CMOS compatible silicon photonics based optomechanics. A simulation study of one such device composed of a graphene membrane suspended over a Si slot waveguide is performed. Several key figure of merits - the zero-point motion, the optomechanical coupling rate and the Brillouin gain of the device are estimated. Also their dependence on the waveguide geometry and the fermi energy of graphene is studied.
