    Different behavior of Nano sheet and Bulk of the hexagonal boron nitride with first principal calculation approach by Abbas FarhadiKoutenaei, Marwa Ali Mahdi, Ali Bahari, Ali Al-Jelif

    Published 2024-02-01
    “…Considering the existence of the low band gap energy between the bottom of the conduction band and the maximum of the valence band, (although the size of the bandgap decreases with the increase in the number of layers), it can be concluded that the samples are semiconductors.Since there is a relationship between refractive index, magnetic permeability, and electrical permeability (magnetic parameters are not discussed in the present work), dielectric function, reflection coefficient, absorption coefficient, and refractive index are also investigated. …”
