New possibilities are presented for the characterization ofAIIIBVmixed superlattice compounds by the complementary use of synchrotron diffraction topography and rocking curves. In particular, using a synchrotron white beam and the section diffraction

Boron nitride films were grown on 2-inch sapphire substrates using the MOCVD technique. The growth was performed using a pulsed source injection mode with triethylborane (TEB) and ammonia (NH3) with a high V/III ratio, which corresponds to the self-t

To meet the requirements for the narrow emission line of ht laser diode pumping system exactly at 808 nm wavelength, an optimization of the laser (AlGa)As heterostructure because of the composition and thickness of the constituent layers is necessary

Lithium niobate crystals doped with Pr3+ or Yb3+, as well as double doped with Yb3+ and Pr3+ ions were pulled by the Czochralski method. The doping concentration spread distributions were measured for each ion by the electron microprobe. The optical

The influence of metallic contaminants (Ni, Mo) on the oxygen precipitation process during high temperature (HT) treatment under hydrostatic pressure (HP) was studied. No significant influence of Ni and Mo contaminants on the oxygen precipitation pro

Optical measurements of semi-insulating GaAs in spectral region 1400 - 500 cm-1 are presented. The new absorption lines X5 (1201.8 cm-1) and X4 (1317.5 cm-1) are observed. It has been found that they are related to electrically active defects and are

Single crystals of LiNbO3:Er3+, LiNbO3:Tm3+, LiNbO3:Er3+ + Tm3+ and LiNbO3:Er3+ + Tm3+ + Mg2+ were grown by the Czochralski method starting from the congruently melting composition. Uniformly doped crystals were obtained at pulling rates 1 - 2 mm/h a
