Optical Signatures of Coupled Quantum Dots
Eric Stinaff,Michael Scheibner,Allan S. Bracker,Ilya Ponomarev,Vladimir L. Korenev,Morgan E. Ware,Matthew F. Doty,Thomas L. Reinecke,Daniel Gammon +8 more
TL;DR: Coulomb interactions shift the molecular resonance of the optically excited state (charged exciton) with respect to the ground state (single charge), enabling light-induced coupling of the quantum dots.
Journal ArticleDOI
Optical pumping of the electronic and nuclear spin of single charge-tunable quantum dots.
Allan S. Bracker,Eric Stinaff,Daniel Gammon,Morgan E. Ware,Joseph G. Tischler,Andrew Shabaev,Al. L. Efros,Doewon Park,David Gershoni,V. L. Korenev,I. A. Merkulov +10 more
TL;DR: The Overhauser effect in a high longitudinal magnetic field is used to demonstrate efficient optical pumping of nuclear spins for all three charge states of the quantum dot.
Journal ArticleDOI
Polarization induced pn-junction without dopant in graded AlGaN coherently strained on GaN
Shibin Li,Morgan E. Ware,Jiang Wu,Paul Minor,Zhiming Wang,Zhiming Wu,Yadong Jiang,Gregory J. Salamo +7 more
TL;DR: In this article, a type of pn-junction not formed by impurity-doping was proposed by grading the Al composition in an AlGa1−xN thin film, resulting in alternating p and n conducting regions due to polarization charge.
Journal ArticleDOI
Polarized fine structure in the photoluminescence excitation spectrum of a negatively charged quantum dot.
Morgan E. Ware,Eric Stinaff,Daniel Gammon,Matthew F. Doty,Allan S. Bracker,David Gershoni,V. L. Korenev,Stefan C. Badescu,Yuli Lyanda-Geller,T. L. Reinecke +9 more
TL;DR: P polarized photoluminescence excitation spectroscopy of the negative trion in single charge-tunable quantum dots exhibits a p-shell resonance with polarized fine structure arising from the direct excitation of the electron spin triplet states.
Journal ArticleDOI
Binding energies of positive and negative trions: From quantum wells to quantum dots
A. S. Bracker,Eric Stinaff,Daniel Gammon,Morgan E. Ware,Joseph G. Tischler,Doewon Park,David Gershoni,A. Filinov,Michael Bonitz,François M. Peeters,C. Riva +10 more
TL;DR: In this paper, the binding energies for positive and negative trions in a series of narrow GaAs quantum wells and in ''natural'' quantum dots defined by quantum well thickness fluctuations were compared.
