Abstract

II-VI semiconductor alloys have recently received considerable attention for their possible use in double heterostructure (DH) blue laser diodes (LDs).1-4 The purpose of this paper is to present the empirical pseudopotential method within virtual crystal approximation for calculating the band structure of MgZnSSe quaternary alloy. The dependence of band gap energies on alloy composition has shown that MgZnSSe can be a direct or an indirect semiconductor. Electron and hole effective masses are calculated for different composition. Camel's back structure for the X valley conduction band has been found for certain composition range.
