Double quantum dot in a quantum dash: optical properties

Piotr Kaczmarkiewicz, Paweł Machnikowski, Tilmann Kuhn

We study the optical properties of highly anisotropic quantum dot structures (quantum dashes) characterized by the presence of two trapping centers located along the structure. Suc…

Carrier trapping in a quantum dash: optical signatures

Piotr Kaczmarkiewicz, Paweł Machnikowski, Tilmann Kuhn

We theoretically study the optical properties and the electronic structure of highly elongated quantum dots (quantum dashes) and show how geometrical fluctuations affect the excito…

Electronic and optical properties in non-uniformly shaped QDashes

Piotr Kaczmarkiewicz, Paweł Machnikowski

We theoretically study the optical properties and the electronic structure of highly elongated quantum dots (quantum dashes) and show how carrier trapping due to geometrical fluctu…

Carrier trapping and luminescence polarization in quantum dashes

A. Musiał, P. Kaczmarkiewicz, G. Sęk +6

We study experimentally and theoretically polarization-dependent luminescence from an ensemble of quantum-dot-like nanostructures with a very large in-plane shape anisotropy (quant…

Second-order polaron resonances in self assembled quantum dots

Piotr Kaczmarkiewicz, Paweł Machnikowski

We theoretically study the optical properties of an InAs/GaAs quantum dot (QD) near the area of the second-order resonance between an electron confined in the QD and two longitudin…

Hole subband mixing and polarization of luminescence from quantum dashes: a simple model

Piotr Kaczmarkiewicz, Anna Musiał, Grzegorz Sęk +3

In this paper, we address the problem of luminescence polarization in the case of nanostructures characterized by an in-plane shape asymmetry. We develop a simple semi-qualitative…

Two-phonon polaron resonances in self-assembled quantum dots

Piotr Kaczmarkiewicz, Paweł Machnikowski

We study the second-order polaronic resonance between 2-LO-phonon states and p-shell electron states in a quantum dot. We show that the spectrum in the resonance area can be quanti…
