We present a theoretical and experimental investigation of exciton recombination dynamics
and the related polarization of emission in highly in-plane asymmetric nanostructures …

Contrary to simplified theoretical models, atomistic calculations presented here reveal that
sufficiently large in-plane shape elongation of quantum dots can not only decrease, but even …

We investigate strongly asymmetric self-assembled nanostructures with one of the
dimensions reaching hundreds of nanometers. Close to the nanowirelike type of …

In this work, we discuss a method to control the polarization anisotropy of spontaneous
emission from neutral excitons confined in quantum-dot-like nanostructures, namely single …

Tunnel-injection lasers promise various advantages in comparison to conventional laser
designs. In this paper, the physics of the tunnel-injection process is studied within a …

We investigated emission properties of photonic structures with InAs/InGaAlAs/InP quantum
dashes grown by molecular beam epitaxy on a distributed Bragg reflector. In high-spatial …

We have investigated optical properties of hybrid two-dimensional-zero-dimensional (2D-
0D) tunnel structures containing strongly elongated InAs/InP (001) quantum dots (called …

The impact of the quantum confinement strength, defined by the width and depth of potential-
energy well for carriers, on properties of correlated electron–hole pairs (excitons) was the …

The InAs/InP quantum dots (QDs) are investigated by time-integrated (PL) and time-resolved
photoluminescence (TRPL) experiments. The QDs are fabricated site-selectively by droplet …

We investigate the electron and hole spin relaxation in an ensemble of self-assembled
InAs/In 0.53 Al 0.24 Ga 0.23 As/InP quantum dots with emission wavelengths around 1.5 μ m …
