X-ray absorption fine structure is investigated in ZnGeP2:Mn crystals at K-edge of Zn, Ge and Mn. Both, the XANES and EXAFS results indicate that Mn atoms substitute on cationic sites in the chalcopyrite structure. It is, however, impossible to discr

Deep levels of single vacancies and antisite defects in the structure of the ZnGeP2 compound are investigated using the pseudopotential method and an extended unit cell. The data obtained are compared with those for the GaP isoelectronic analog. It i

Ternary diamond-like compounds in II–IV–V2 semiconductor system heavily-doped with transition d-element Mn have been recently prepared. The materials grown in both forms — single crystal layers and polycrystalline bulks — exhibit well defined

The growth of quaternary solid solutions in the ZnGeP 2 -Mn quasi-binary system was studied. Single-crystal thin layers of ZnGeP 2 :Mn with a basal crystal structure appurtenant to the chalcopyrite crystal class were grown for the first time. Ferroma

The existing coherent light sources are nonuniformly distributed by frequency in the optical range. Thus, work toward the development of tunable lasers operating in the middle IR range has long been underway. Nevertheless, the region 4–8 µm has be

The magnetic site-inequivalence of the both Zn sites in ZnGeP2 (ZnSiP2) could be resolved for MnZn2+ (S = ) by electron paramagnetic resonance (EPR) measurements. The EPR spectra are analyzed with the generalized spin Hamiltonian (SH) for S4 symmetry

The interaction between ultrasound and macroscopic defects in solids is considered using the nonlinear theory of elasticity. It is shown that, due to the resonance nature of the vibrations of the defect, considerable anharmonism occurs even when the
