“…These critical features are qualitatively comparable to results from other theoretical calculations. 31,37,42,43,46 The drastic difference between our calculated band gap and the others precludes any quantitative agreement. There is no experimental report, known to us, on these critical features for zb-BP.…”

We present results from ab-initio, self-consistent density functional theory calculations of electronic and related properties of zinc blende boron phosphide (zb-BP). We employed a local density approximation potential and implemented the linear combination of atomic orbitals formalism. This technique follows the Bagayoko, Zhao, and Williams method, as enhanced by the work of Ekuma and Franklin. The results include electronic energy bands, densities of states, and effective masses. The calculated band gap of 2.02 eV, for the room temperature lattice constant of a = 4.5383 Å, is in excellent agreement with the experimental value of 2.02 ± 0.05 eV. Our result for the bulk modulus, 155.7 GPa, agrees with experiment (152–155 GPa). Our predictions for the equilibrium lattice constant and the corresponding band gap, for very low temperatures, are 4.5269 Å and 2.01 eV, respectively.

“…Semiconductors are used in a variety of remarkable device applications. Superlattices have been made available for use in many applications owing to developments in their production techniques, such as the strain-induced lateral ordering process [1,2], molecular beam epitaxy [2,3] and low-pressure chemical-vapor deposition [2,4]. The development of superlattices is actively being researched by studying the properties of superlattices with reduced size and dimensionality and by understanding their properties within the context * E-mail: rachdj@yahoo.fr of designing new electronic and optoelectronics devices.…”

“…Superlattices (SLs) are structures that are made up of two types of semiconducting (s.c) materials, with one type (s.c 1 ) acting as a quantum well and the other (s.c 2 ) acting as a quantum barrier [2]. In the present work, we explore the structural and electronic properties of the II-VI semiconductor compounds BeTe and ZnSe.…”

The structural, electronic and optical properties of (BeTe) n /(ZnSe) m superlattices have been computationally evaluated for different configurations with m = n and m = n using the full-potential linear muffin-tin method. The exchange and correlation potentials are treated by the local density approximation (LDA). The ground state properties of (BeTe) n /(ZnSe) m binary compounds are determined and compared with the available data. It is found that the superlattice band gaps vary depending on the layers used. The optical constants, including the dielectric function ε(ω), the refractive index n(ω) and the refractivity R(ω), are calculated for radiation energies up to 35 eV.

“…The superlattice is thus a periodic structure with period d = L w + L b . The artificial periodicity created in superlattices can lead to the tailoring of certain material properties for applications in fields such as optoelectronics [3,4]. The presence of these ultrathin layers leads to the quantum size effect when the physical dimensions of the layers are comparable to the de Broglie wavelength of the charge carrier [5].…”
