In this work, we report our results on the geometric and electronicproperties of hybrid graphite-like structure made up of silicene and boronnitride (BN) layers. We predict from our calculations that this hybrid bulksystem, with alternate layers of honeycomb silicene and BN, possesses physicalproperties similar to those of bulk graphite. We observe that there exists aweak van der Waals interaction between the layers of this hybrid system incontrast to the strong inter-layer covalent bonds present in multi-layers ofsilicene. Furthermore, our results for the electronic band structure and thedensity of states show that it is a semi-metal and the dispersion around theFermi level (E_F) is parabolic in nature and thus the charge carriers in thissystem behave as \textit{Nearly-Free Particle-Like}. These results indicatethat the electronic properties of the hybrid bulk system resemble closely thoseof bulk graphite. Around E_F the electronic band structures have contributionsonly from silicene layers and the BN layer act only as a buffer layer in thishybrid system since it does not contribute to the electronic properties nearE_F. In case of bi-layers of silicene with a single BN layer kept in between,we observe a linear dispersion around E_F similar to that of graphene. However,the characteristic linear dispersion become parabola-like when the system issubjected to a compression along the transverse direction. Our presentcalculations show that the hybrid system based on silicon and BN can be apossible candidate for two dimensional layered system akin to graphite andmulti-layers of graphene.
