Quasi-two-dimensional excitons in (Zn,Cd)Se/ZnSe quantum wells : reduced exciton-LO-phonon coupling due to confinement effects
Nikos T. Pelekanos,J. Ding,M. Hagerott,Arto V. Nurmikko,H. Luo,Nitin Samarth,Jacek K. Furdyna +6 more
TL;DR: Quasi-two-dimensional excitons in (Zn,Cd)Se/ZnSe quantum wells were investigated and observed a confinement-induced enhancement of the exciton binding energy to a value greater than the longitudinal-optical (LO) -phonon energy.
Journal ArticleDOI
Zinc‐blende MnTe: Epilayers and quantum well structures
Stephen M. Durbin,Jung Han,Sungki O,Masakazu Kobayashi,D. R. Menke,Robert L. Gunshor,Q. Fu,Nikos T. Pelekanos,Arto V. Nurmikko,D. Li,J. M. Gonsalves,Nobuo Otsuka +11 more
TL;DR: In this paper, a series of strained single quantum well structures was fabricated with zinc-blende MnTe forming the barrier to CdTe quantum well regions; photoluminescence spectra indicate optical transitions corresponding to strong electron and hole confinement.
Journal ArticleDOI
Room‐temperature exciton absorption in (Zn,Cd)Se/ZnSe quantum wells at blue‐green wavelengths
TL;DR: In this paper, the n=1 heavy hole exciton was investigated in multiple quantum wells of (Zn,Cd)Se/ZnSe in an effort to increase the electron-hole Coulomb interaction.
Journal ArticleDOI
Preferential nucleation of GaN quantum dots at the edge of AlN threading dislocations
TL;DR: In this article, the authors reported on transmission electron microscopy and optical characterization of GaN dots embedded in an AlN matrix, which were grown by molecular beam epitaxy on top of an alN layer deposited on (0001) sapphire.
Journal ArticleDOI
Room temperature observation of biexcitons in exfoliated WS2 monolayers
Ioannis Paradisanos,Ioannis Paradisanos,S. Germanis,Nikos T. Pelekanos,Nikos T. Pelekanos,Costas Fotakis,Costas Fotakis,Emmanuel Kymakis,Emmanuel Kymakis,George Kioseoglou,George Kioseoglou,Emmanuel Stratakis,Emmanuel Stratakis +12 more
TL;DR: In this paper, the existence of biexcitons in mechanically exfoliated WS2 flakes from 78'K up to room temperature was investigated. But the bieciton emission channel was not identified through the superlinear behavior of the integrated photoluminescence intensity as a function of the excitation power density.
