Interlayer interactions perturb the electronic structure of two-dimensional materials and lead
to new physical phenomena, such as van Hove singularities and Hofstadter's butterfly
pattern. Silicene, the recently discovered two-dimensional form of silicon, is quite unique, in
that silicon atoms adopt competing sp 2 and sp 3 hybridization states leading to a low-
buckled structure promising relatively strong interlayer interaction. In multilayer silicene, the
