Abstract
This study focuses on investigating the structural, electronic and optical properties of BN using first-principles analysis.
To form a zinc-blende superlattice oriented following (001), (111), an ultrathin XY layer (where X = B, Al and Y = Bi, P, N)
is inserted into the BN structure, using the full potential linear muffin-tin orbitals method (FPLMTO) within generalized
gradient approximation (GGA96). Electronic structure analysis confirms that these compounds exhibit semiconductor
behavior when oriented along the (001) axis with a direct (AlN)1/(BN)1 and indirect difference for the two other SLs. The
analysis of the partial density of states reveals a significant influence of nitrided materials, such as BN, which can be
attributed to the strong sp hybridization of N atoms. Furthermore, the dielectric functions, refractive index, and calculated
absorption spectra of the (001) oriented superlattices demonstrate their potential for various technological applications in
infrared and visible emission. We have found that our calculated values were in good agreement with those in the
literature. In contrast, the (111) oriented systems exhibit semi metallic behavior. No experimental or theoretical studies
have been conducted on the properties of (111)-oriented superlattices (SLs) composed of (BBi)1/(BN)1, (BP)1/(BN)1 and
(AlN)1/(BN)1. So, this theoretical study provides valuable insight that can help in experimental measurements.
