Abstract: | The electronic band structure of GaxIn1-xAs alloy is calculated by using the local empirical pseudo-potential method including the effective disorder potential in the virtual crystal approximation.The compositional effect of the electronic energy band structure of this alloy is studied with composition x ranging from 0 to 1.Various physical quantities such as band gaps,bowing parameters,refractive indices,and high frequency dielectric constants of the considered alloys with different Ga concentrations are calculated.The effects of both temperature and hydrostatic pressure on the calculated quantities are studied.The obtained results are found to be in good agreement with the available experimental and published data. |
