Quantum Wire - Quantum Dot Systems Grown in Inverted Pyramids

Justyna Szeszko

Semiconductor quantum wires (QWRs) and quantum dots (QDs) are nanoscale heterostructures, which form fascinating low-dimensional systems for fundamental studies of quantum-mechanical effects and are attractive candidates for integration into optoelectronic ...

Superfluidity with disorder in a thin film of quantum gas

Jean-Philippe Brantut

We investigate the properties of a strongly interacting superfluid gas of 6Li2 Feshbach molecules forming a thin film confined in a quasi-two-dimensional channel with a tunable random potential, creating a microscopic disorder. We measure the atomic curren ...

Exciton Formation, Relaxation, and Decay in PCDTBT

Natalie Renuka Banerji, Eric Vauthey

The nature and time evolution of the primary excitations in the pristine conjugated polymer, PCDTBT, are investigated by femtosecond-resolved fluorescence up-conversion spectroscopy. The extensive study includes data from PCDTBT thin film and from PCDTBT i ...

All the Disorder Mechanisms in the 13:58 Phases Come Together. Out of the Modulated Confusion Rises the Remarkable Phase Ce12.60Cd58.68(2)

The compound

Ce_{12.60}Cd_{58.68(2)}

is a metrically commensurate representative of the incommensurately modulated phase

Ce_{13}Cd_{57+\delta}

. It is most likely a lock-in phase. The structure, which was solved using seeding of the modulation from thos ...

Synchronized and Desynchronized Phases of Exciton-Polariton Condensates in the Presence of Disorder

Benoît Marie Joseph Deveaud, Konstantinos Lagoudakis

Condensation of exciton polaritons in semiconductor microcavities takes place despite in-plane disorder. Below the critical density, the inhomogeneity of the disorder limits the spatial extension of the ground state. Above the critical density, in the pres ...

Realistic heterointerface model for excitonic states in growth-interrupted GaAs quantum wells

Vincenzo Savona

We present a model for the disorder of the heterointerfaces in GaAs quantum wells including long-range components like monolayer island formation induced by the surface diffusion during the epitaxial growth process. Taking into account both interfaces, a d ...
