(author), Kondo, K. (author), Tomioka, K. (author), Fukui, T. (author), Suemune, I. (author), Zwiller, V. (author)We have investigated the optical properties of a single InAsP quantum dot embedded in a standing InP nanowire. Elongation of the transverse exciton-spin relaxation time of the exciton state with decreasing excitation power was observed by first-order photon correlation measurements. This behavior is well explained by the motional narrowing...journal article 2012

(author), Zwiller, V. (author), Suemune, I. (author)We report the experimental demonstration of single-photon and cascaded photon pair emission in the infrared, originating from a single InAsP quantum dot embedded in a standing InP nanowire. A regular array of nanowires is fabricated by epitaxial growth on an electron-beam patterned substrate. Photoluminescence spectra taken on single quantum...journal article 2010

(author)We report on the fabrication of a dual-gated single-electron transistor (SET) based on a quantum dot (QD) formed by selective area growth of metalorganic vapor-phase epitaxy, and its low-temperature transport properties. We observe clear Coulomb oscillations in a SET fabricated in combination with direct growth of nanostructures and...journal article 2002
