A comparative understanding concerning to electrical properties of recent developed materials Se-Zn-In and Se-Zn-Te-In could be helpful to outline their potential applications. Therefore it worth to described a relative variation in I-V characteristics, electrical conductivity and ln(I) vs V1/2 characteristics for the Se98-xZn2Inx (0 ≤ x ≤ 10) and Se93-xZn2Te5Inx (0 ≤ x ≤ 10) chalcogenide glasses. Obtained outcome demonstrates the incorporation of fixed amount of Te with increasing In concentration as cost of Se affects the structural unit values and electrical properties. The electrical properties of the subjected materials have been obtained higher correspond to chemical thresholds structural units values.</li></ul>http://www.seipub.org/aom/PaperInfo.aspx?ID=6463Advances in Optoelectronic Materialshttp://www.seipub.org/aom/PaperInfo.aspx?ID=64632014-0<p class="abstract">Tran Blaha Modified Becke-Johnson Potential Band Structure Including Spin Orbit Interaction</p><ul><li>Pages 10-17</li><li>Author S. KumarSuman PandeyS. Auluc</li><li>Abstract We have used full potential linear augmented plane wave method within density functional theory to study the electronic and optical properties of Cu-based chalcopyrite semiconductors CuXS2 (X=Al, Ga, In). Tran-Blaha modified Becke-Johnson (TB-mBJ) potential are used to find out the suitability for the study of optical properties. We discuss the improvement in energy band gap determination using TB-mBJ compared to the standard generalized gradient approximation (GGA) and Engel Vosko’s generalized gradient approximation (EV-GGA) within density functional theory. The calculated crystal field splitting energy decreases with increasing III- group cation’s atomic number i.e. Al→In. The magnitude of spin-orbit coupling energy remains almost same for all the three systems. The obtained dielectric functions using TB-mBJ show good agreement with the available experimental data.</li></ul>http://www.seipub.org/aom/PaperInfo.aspx?ID=11656Advances in Optoelectronic Materialshttp://www.seipub.org/aom/PaperInfo.aspx?ID=11656
