Stringfellow, Gerald B.; Shurtleff, James Kevin | Heterostructures in GaInP grown using a change in Te doping | In organometallic vapor phase epitaxy, changes in growth conditions can be used to modulate the extent of CuPt ordering and, hence, the band gap energy of GaInP. One method is to add Te during growth. An increase in the band gap energy of 0.1 eV due to a decrease in ordering has been obtained by ... | Heterostructures; Alloys | 2000 |
