Dominant role of many-body effects on the carrier distribution function of quantum dot lasers [PDF]
, 2016 The effects of free-carrier-induced shift and broadening on the carrier distribution function are studied considering different extreme cases for carrier statistics (Fermi–Dirac and random carrier distributions) as well as quantum dot (QD) ensemble ...

Model-independent determination of the carrier multiplication time constant in CdSe nanocrystals [PDF]
, 2009 The experimental determination of the carrier multiplication (CM) time constant is complicated by the fact that this process occurs within the initial few hundreds of femtoseconds after excitation and, in transient-absorption experiments, cannot be ...

Identification of the hereditary pyropoikilocytosis carrier state [PDF]
Blood, 1984 Abstract We evaluated the hematologic, rheologic, and biochemical features of erythrocytes obtained from 10 relatives of a 5-yr-old black female with hereditary pyropoikilocytosis (HPP) and severe hemolytic anemia. Erythrocyte morphology was normal in the father and five other relatives, but ghost mechanical fragility and drug-induced ...

Towards automated design of quantum cascade lasers [PDF]
, 2005 We present an advanced technique for the design and optimization of GaAs/AlGaAs quantum cascade laser structures. It is based on the implementation of the simulated annealing algorithm with the purpose of determining a set of design parameters that ...

Secure Quantum Secret Sharing Based on Reusable GHZ States as Secure Carriers [PDF]
, 2006 We show a potential eavesdropper can eavesdrop whole secret information when the legitimate users use secure carrier to encode and decode classical information repeatedly in the protocol [proposed in Bagherinezhad S and Karimipour V 2003 Phys. Rev.

Charge carrier correlation in the electron-doped t-J model
, 2006 We study the t-t'-t''-J model with parameters chosen to model an electron-doped high temperature superconductor. The model with one, two and four charge carriers is solved on a 32-site lattice using exact diagonalization.

On the interface polaron formation in organic field-effect transistors
, 2010 A model describing the low density carrier state in an organic single crystal FET with high-$\kappa$ gate dielectrics is studied. The interplay between charge carrier coupling with inter-molecular vibrations in the bulk of the organic material and the ...

Disorder-induced noncollinear ferromagnetism in models for (III,Mn)V semiconductors [PDF]
, 2002 We study the ground state properties of kinetic-exchange models for (III,Mn)V semiconductors with randomly distributed Mn ions. Our method is embedded in a path integral spin-wave type formalism leading to an effective action for Mn spins only with full ...

Quantum coherence and carriers mobility in organic semiconductors
, 2007 We present a model of charge transport in organic molecular semiconductors based on the effects of lattice fluctuations on the quantum coherence of the electronic state of the charge carrier. Thermal intermolecular phonons and librations tend to localize
