The change of emerge-band gap of In_xGa_1-xAs ternary alloys grown on GaAs substrate was calculated theoretically. The band structure of epitaxial layer was affected by strain due to differences between the film and substrate lattice constants. Strains in the layer varied almost linearly with composition. It was indicated that the bandgap of strained In_xGa_1-xAs increased and valence band splitting occurred, compared to unstrained materials. This makes it possible to control the bandgap by altering the alloys composition and hence strain. It is useful to the devices design.
