ABSTRACT

Langasite single crystal was grown by Xenon-arc floating zone method in mixutre of Ar and O2 gas atmosphere.Growing and rotation speed were 1.5 m/h and 15 rpm respectively. The grown crystal had a c-axis and color of orange.Composition of the grown crystal was La3.10Ga4.73Si1.17O14. Activation energy of the crystal was 0.23 eV and was PTCcharacteristics.Key words Langasite, Floating zone, Activation energyFloating zone .. ...
