Indirect excitons (IX) in semiconductor heterostructures are bosons, which can cool below
the temperature of quantum degeneracy and can be effectively controlled by voltage and …

Electrically controlled photonic circuits hold promise for information technologies with greatly
improved energy efficiency and quantum information processing capabilities. However …

Excitons hosted by GaN/(Al, Ga) N quantum wells (QWs) are spatially indirect due to the
giant built-in electric field that separates electrons and holes along the growth direction. This …

Dipolar coupling plays a fundamental role in the interaction between electrically or
magnetically polarized species such as magnetic atoms and dipolar molecules in a gas or …

A giant built-in electric field in the growth direction makes excitons in wide GaN/(Al, Ga) N
quantum wells spatially indirect even in the absence of any external bias. Significant …

We investigate the electronic and optical properties of a confined exciton in CdS/CdSe/CdS
asymmetric quantum well taking into account the geometrical confinement in which the right …

Indirect excitons (IXs) are bound pairs of electrons and holes confined in spatially separated
layers. We present wide single quantum well (WSQW) heterostructures with high IX mobility …

We present a concept and experimental proof of principle for split-gate devices for indirect
excitons (IXs). The split-gate forms a narrow channel, a point contact, for IX current. Control …

We report on the observation of a significant increase of the radiative decay rates for exciton
transitions in a wide (In, Ga) As/GaAs quantum well (L= 95 nm) in magnetic fields up to 6 T …

We present an experimental study on optical properties and dynamics of direct and spatially
and momentum indirect excitons in AlGaAs/AlAs quantum wells near the crossover between …
