Here we focus on possible exotic superconductivity (SC) in the monolayer and bilayer silicene. For the former system, we found an electric-field driven quantum phase transition (QPT) from chiral d+id to f-wave SC. For the latter system, we found that even the undoped system is intrinsically metallic and superconducting with tunable Tc which can be high. Our study helps to set a bridge between the exotic unconventional SC and the familiar Si industry.  Journal Ref: Feng Liu, et al, Phys. Rev. Lett. 111, 066804 (2013).
