Disordered quantum antiferromagnetism in doped semiconductors: Density of states approach
N. A. Bogoslovskiy, P. V. Petrov, N. S. Averkiev
We present a theoretical study of the exchange interaction in a system of spatially disordered magnetic moments. A typical example of such a system is an impurity semiconductor, wh…
Phase diagram of a ferromagnetic semiconductor. The origin of superparamagnetism
N. A. Bogoslovskiy, P. V. Petrov, N. S. Averkiev
We study the theoretical model of a ferromagnetic semiconductor as a system of randomly distributed Ising spins with a long-range exchange interaction. Using the density-of-states…
Two components of donor-acceptor recombination in compensated semiconductors. Analytical model of spectra in presence of electrostatic fluctuations
N. A. Bogoslovskiy, P. V. Petrov, Yu. L. Ivanov K. D. Tsendin +1
We report numerical and analytical studies of the donor-acceptor recombination in compensated semiconductors. Our calculations take into account random electric fields of charged i…
Optical spectroscopy of single beryllium acceptors in GaAs/AlGaAs quantum well
P. V. Petrov, I. A. Kokurin, G. V. Klimko +5
We carry out microphotoluminescence measurements of an acceptor-bound exciton (A^0X) recombination in the applied magnetic field with a single impurity resolution. In order to desc…
Optical orientation of spins in GaAs:Mn/AlGaAs quantum wells via impurity-to-band excitation
P. V. Petrov, I. A. Kokurin, Yu. L. Ivanov +5
The paper reports optical orientation experiments performed in the narrow GaAs/AlGaAs quantum wells doped with Mn. We experimentally demonstrate a control over the spin polarizatio…
