Abstract :
In this work, based on the Density Function Theory we studied the Borne Phosphide honey-combe structure and for comparing the dimensionality effects, we performed a brief study about its three-dimension (bulk) too. Theses first-principles calculations obtained an indirect band gap for 3D of Bp where it obtained one direct (about 0.9024 eV) for its honey-combe structure that is transparent for vertical polarization beam with a selection ability in transmitance/ adsorbance and reflectance for horizontal polarization. The obtained band gaps are near to repports. As a new work, by adsorption of Si at four outstanding positions on the honey-combe structure of Bp we studied its electrical and optical propertis where the omitting of band gap and pseudo-metaling of structure was a superior result for Si adsorption. for improvement of calculation results we used the Modified Becke–Johnson potential proposed by Tran and Blaha (TB-MBJ).
