| Abstract | The effect of single crystals growth conductions on the optical transmission spectra and electrophysical properties of La3Ga5SiO14 (langasite, LGS) and La3Ta0,5Ga5,5O14 (langatate, LGT) crystals has been studied. Investigations of the temperature dependences of electrical conduction of langatate in the 20-500 oC temperature range in a constant electric field have been conducted. The effect of conducting coating material on these dependences has been investigated. The experiment required Y-cut samples made from crystals grown in argon (Ar) and argon/oxygen (Ar+O2) atmospheres. The conducting coating materials were iridium(Ir) gold with а titanium sublayer (Au(Ti)) and silver with а chromium sublayer (Ag(Cr)). |
