Composition dependence of energy gap in GaInAs alloys

Abstract
The energy gap of GaInAs alloys, grown by vapor‐phase epitaxial growth using organometallic sources of Ga and In, has been measured over the composition range 0–50 mole% InAs. The energy gap is found to vary linearly with composition. Comparison with data in the literature indicates that highly homogeneous layers can be obtained by the organometallic growth technique.
