Claim:
1. A method of incorporating indium onto a growth film at an elevated growth temperature comprising: providing a growth film; depositing a buffer layer on the growth film; placing the growth film in an organometallic vapor phase epitaxy (OMVPE) growth environment having an elevated growth temperature; flowing a vapor comprising gallium and indium into the growth environment; adding antimony (Sb) at least at or above a critical concentration level into the vapor; and allowing the vapor to flow to maintain a growth phase for a period of time; wherein after said growth phase and said period of time an indium incorporation fraction is at least 0.20 on a resultant growth film; and wherein adding the antimony at least at or above the critical concentration level results in an abrupt change in bandgap energy.
