The paper deals with the kinetics of the droplet epitaxial GaAs quantum ring formation grown on AlGaAs (0 0 1) surface. The observation is, that the aspect ratio of these nano structures is depends not only on the technological parameters but on the

Recently, the growth of self-assembled quantum structures has been intensively investigated for basics physics and device application. In our work, self-assembled strain-free GaAs quantum dots and quantum rings were investigated by the photoluminesce

In this work, droplet epitaxially grown GaAs quantum dots on AlGaAs surface are studied. The quantum dots are investigated in situ with RHEED and ex situ with TEM method. The TEM picture shows that the quantum dot is perfectly crystalline and fits ve

We have studied the optical properties of droplet epitaxial quantum dots and quantum rings in the GaAs/GaAlAs system. Photoluminescence spectra measurements were performed in the temperature range from 4 to 300 K. The differences between the observed

In this work novel three-dimensional metamaterials are realized by rolling-up strained metal/semiconducting nanolayers. The properties of these artifcial, optical crystals can be described by efective parameters, which are investigated by numerical s
