Hybrid organic–inorganic perovskites have emerged as a new class of semiconductors that
exhibit excellent performance as active layers in photovoltaic solar cells. These compounds …

The studies of spin phenomena in semiconductor low-dimensional systems have grown into
the rapidly developing area of the condensed matter physics: spintronics. The most urgent …

Coherent manipulation of quantum bits (qubits) on timescales much shorter than the
coherence time, is a key prerequisite for quantum information processing. Electron spins in …

In recent years, the physics community has experienced a revival of interest in spin effects in
solid state systems. On one hand, the solid state systems, particularly, semiconductors and …

We measure the frequency spectra of random spin fluctuations, or “spin noise,” in
ensembles of (In, Ga) As/GaAs quantum dots (QDs) at low temperatures. We employ a spin …

The hyperfine interaction of an electron with the unpolarized nuclei in thermally annealed
self-assembled InAs/GaAs quantum dots (QDs) is theoretically analyzed. For this purpose …

The band structure of type-I (In, Al) As/AlAs quantum dots with band gap energy exceeding
1.63 eV is indirect in momentum space, leading to long-lived exciton states with potential …

The coherent electron spin dynamics of an ensemble of singly charged (In, Ga) As/GaAs
quantum dots in a transverse magnetic field is driven by periodic optical excitation at 1 GHz …

The g-factor tensors of electron and hole in self-assembled (In, Ga) As/GaAs quantum dots
are studied by time-resolved ellipticity measurements in a three dimensional vector magnet …
