چکیده

In order to enhance the viability of this paper for that issue, we suggest adding this to the beginning of the abstract: “Binary semiconductors with (AB and AB) composition and ternary semiconductors (ABC2 and ABC2) composition, owing to their devices such as photonic crystals, wave guides, solar cells and detectors, are technologically important materials. The recent successful fabrication of the blue-green laser diode based on these compounds has renewed interest in their opto-electronic properties. In this paper we present a relationship to evaluate opto-electronic properties such as electronic polarizability (α), refractive index (n), band gap (Eg) and optical electronegativity (∆χ*) in terms of product of ionic charges (PIC) and average atomic number of constituent atoms (Zav) for zinc blende (AB and AB) and chalcopyrites (ABC2 and ABC2) structured solids. The electronic polarizability (α), refractive index (n), band gap (Eg) and optical electronegativity (∆χ) of these solids exhibit a linear relationship when plotted against the average atomic number constituent atoms (Zav), but fall on different lines due to the region of product of the ionic charges (PIC) of the compounds. We have applied the proposed relation on these solids and found a better agreement with the experimental data as compared to the values evaluated by earlier researchers so far.

Hydrogen in compound semiconductors

Hydrogen can be inadvertently introduced at any of several steps in the fabrication of optoelectronic devices. The most common consequence of hydrogenation is the passivation of dopant impurities, which leads to a decrease in the electrical conductivity of the material. The most successfully applied experimental technique for directly determining the involvement of hydrogen has been infrared-ab...
