| Abstract: | Using the plasma oscillation theory of solids, simple relations have been proposed for the calculation of the homopolar (Eh), heteropolar (Ec) and average energy (Eg) gaps, ionicity (fi) and dielectric constant (ε) of II-VI (R,W, Zb), III-V (W, Zb) and I-VII (R) groups of materials with rocksalt (R), wurtzite (W) and zincblende (Zb) structures from their plasmon energy (ħωp). The calculated values of Eh, Ec, Eg, fi and ε are compared with the experimental values and the values reported by earlier researchers. A fairly good agreement has been obtained between them. |
