AbstractStudies of background donor concentration (BDC) in HgCdTe samples grown with different types of technology were performed with the use of ion milling as a means of eliminating the compensating acceptors. In bulk crystals, films grown with liquid phase epitaxy and films fabricated with molecular beam epitaxy (MBE) on Si substrates, BDC of the order of ~10

ABSTRACTThe luminescence properties of undoped GaAs-Ga1−x Alx As layers grown by liquid phase epitaxy (LPE) and molecular beam epitaxy (MBE) are compared for double heterostructure and multiquantum well (MQW) superlattices. Low temperature cathodoluminescence and scanning transmission electron microscopy are used to identify the main luminescence centers and in some instances establish their origin. The possible effects of the observed luminescence features on the degradation process in GaAs-Gal−x Alx As laser devices grown by MBE and LPE are also discussed.

AbstractRelaxation losses of magnetic excitations in nanoscale films of Y_3Fe_5O_12 (YIG) were studied. The films were obtained by laser molecular-beam epitaxy (LMBE). Ferromagnetic resonance linewidth Δ H was found to increase sharply as the temperature decreased from 300 to 77 K. The observed growth of Δ H is explained by typical relaxation processes caused by the presence of Fe^2+ ions. This effect is not observed in thick films of YIG grown by liquid-phase epitaxy and containing Pb^4+ ions, and, hence, we have concluded that the presence of acceptor ions in YIG films obtained by LMBE will facilitate decreasing the concentration of Fe^2+ ions and, a result, diminishing relaxation losses.
