“…However, this method of calculation of the structure factor is almost equivalent to the calculations performed by Lin-Chung (it becomes obvious if one compares Eq. (9) in [31] with Eq. (1) in [26]).…”

The simplifications of the Zn 3 P 2 -type crystal structure having tetragonal symmetry D 15 4h have been analysed. After description of the real unit cell the following simplifications are proposed: tetragonal symmetry (ideal and D 17 4h ), cubic symmetry and the correct molecular ratio (approximations O 9 h , T 7 h and O 4 h ) and finally the zincblende and antifluorite approximations. In the second part we present the results of energy band calculations for fully symmetric Zn 3 P 2 and for all the simplifications. The symmetry of bands is also determined for the full crystal structure and for the ideal approximation. In the calculations the nonlocal empirical pseudopotential method has been used.

“…Two marginal cases are the maximal anisotropy if | α |−→ 1 and the full isotropy if | α |−→ 0. Equation (13) is written in the atomic units of length 11,12); ε ⊥ ; ε are two dielectric constants normal to the main crystalline c-axis and along that, respectively. In our calculation there was accepted a simple supposition: ε = ε ∞ = n 2 ∞ , ε ⊥ = ε ⊥∞ = n 2 ⊥∞ and ε ⊥ =15.13 [32].…”

“…Now II-V compounds have come to show strong promise of constituting the next generation of electronic materials. Among these, zinc phosphide (Zn 3 P 2 ), the constituent elements of which are known to be present in abundant deposits near the surface of the earth, is drawing particularly strong attention as a material which it is hoped will make it possible to produce highly efficient solar cells, sensors, lasers and the like at low cost [12][13][14][15].…”

Theoretical study of excitons spectra is offered in this report as for Zn 3 P 2 crystals. Spectra are got in the zero approach of the theory of perturbations with consideration of both the anisotropy of the dispersion law and the selection rules. The existence of two exciton series was found, which corresponds to two valence bands (hh, lh) and the conductivity band (c). It is noteworthy that anisotropy of the dispersion law plus the existence of crystalline packets (layers) normal to the main optical axis, both will permit the consideration of two-dimensional excitons too. The high temperature displaying of these 2D-exciton effects is not eliminated even into bulk crystals. The calculated values of the binding energies as well as the oscillator's strength for the optical transitions are given for a volume (3D) and for two-dimensional (2D) excitons. The model of energy exciton transitions and four-level scheme of stimulated exciton radiation for receiving laser effect are offered.

“…Zinc phosphide (Zn 3 P 2 ) is an important optoelectronic material, which also has applications in lithium ion batteries [71]. It is an important semiconductor from the II-V group, and is used for optoelectronic applications [13,[72][73][74]. Zinc phosphide exhibits favorable optoelectronic properties, such as direct bandgap of 1.5 eV, which corresponds to the optimum solar energy conversion range [74][75][76][77].…”

“…Zinc, as well as phosphorous, is abundant in the earth's crust. This makes their cost-effective development quite feasible when it comes to large scale production [73,79]. Zinc phosphide is a tetragonal p-type low cost material with lattice constants of a = b =8.097 Å and c=11.45 Å [17] and has all the right characteristics for photo conversion.…”
