Site-controlled growth of single IpP QDs

The MOVPE growth of InP/GaInP quantum dots (QDs) on GaAs substrate "defects" formed by a focused beam of [Ga.sup.+] ions is studied. It is shown that ordered arrays of QDs with a density of 0.25 [(µm).sup.-2] can be obtained in the InP/GaInP system. It is demonstrated that effective lumine...

Description
Summary:The MOVPE growth of InP/GaInP quantum dots (QDs) on GaAs substrate "defects" formed by a focused beam of [Ga.sup.+] ions is studied. It is shown that ordered arrays of QDs with a density of 0.25 [(µm).sup.-2] can be obtained in the InP/GaInP system. It is demonstrated that effective luminescence can be obtained by using two QD sheets separated by a GaAs/GaInP buffer layer. DOI: 10.1134/S1063782615080230
