We report the growth of lattice-matched InGaP/GaAs heterostructures by metalorganic chemical vapour deposition (MOCVD) using TEA and TBP as group V sources. Transmission electron microscopy and X-ray diffraction showed that InGaP is ordered. Photoluminescence measurements at 13 K showed an emission at 1.917 eV which is close to the band gap reported for ordered InGaP. Shubnikov-De Haas oscillations observed at 4.2 K confirmed the presence of two-dimensional electron gas at the interface of this heterostructure. No persistent photoconductivity was observed in these structures.
