Journal ArticleDOI
Coupling and Entangling of Quantum States in Quantum Dot Molecules
Manfred Bayer,Pawel Hawrylak,Karin Hinzer,Karin Hinzer,Simon Fafard,Marek Korkusinski,Marek Korkusinski,Z. R. Wasilewski,O. Stern,Alfred Forchel +9 more
TL;DR: The electron-hole complex is shown to be equivalent to entangled states of two interacting spins in a pair of vertically aligned, self-assembled quantum dots.
Journal ArticleDOI
Terahertz quantum cascade lasers operating up to ∼ 200 K with optimized oscillator strength and improved injection tunneling
Saeed Fathololoumi,Emmanuel Dupont,Chun Wang Ivan Chan,Z. R. Wasilewski,S. R. Laframboise,Dayan Ban,Alpár Mátyás,Christian Jirauschek,Qing Hu,H. C. Liu +9 more
TL;DR: A new temperature performance record of 199.5 K for terahertz quantum cascade lasers is achieved by optimizing the lasing transition oscillator strength of the resonant phonon based three-well design with nearly perfect alignment of the states across the injection and extraction barriers at the design electric field.
Journal ArticleDOI
Addition spectrum of a lateral dot from Coulomb and spin-blockade spectroscopy
M. Ciorga,M. Ciorga,A. S. Sachrajda,Pawel Hawrylak,Charles Gould,Charles Gould,P. Zawadzki,S. Jullian,Y. Feng,Z. R. Wasilewski +9 more
TL;DR: In this paper, Coulomb blockade measurements are performed on a class of electrostatically defined lateral dots within a high mobility two-dimensional electron gas (2DEG) and the design allows Coulomb-blockade (CB) measurements on a single lateral dot containing 0, 1 to over 50 electrons.
Journal ArticleDOI
Size and shape engineering of vertically stacked self-assembled quantum dots
TL;DR: In this article, a new procedure for the growth of stacked self-assembled quantum dot layers is described, where the main effect is to convert the quantum dot population into a population of quantum disks of approximately equal height.
Journal ArticleDOI
Quantum dot infrared photodetectors
TL;DR: In this paper, the authors used state-filling photoluminescence experiments to probe the zero-dimensional states and revealed four atomic-like shells (s,p,d,f) with an excitonic inter-sublevel energy spacing which was adjusted to ∼60 meV.
