Abstract:

High quality fluoride and oxide single crystals for optical, piezoelectric and other applications have been grown by advanced crystal growth techniques. Corquitiite- and Perovskite-type fluoride single crystals - LiCaAlF6, LiSrAlF6, KMgF3 and BaLiF3 - have been grown for solid state UV laser applications, and as window materials for next generation optical lithography. La3Nb0.5Ga5.5O14 and La3Ta0.5Ga5.5O14 piezoelectric single crystals of size and quality comparable to La3Ga5SiO14 langasite, have been produced. The piezoelectric and device properties of the crystals were investigated. A search for new langasite-type materials was also performed. Promising new structural materials, Al2O3RE3Al5O12 RErare earth eutectic fibers, have been grown by the micro-pulling-down micro-PD technique. Undoped and doped Beta-Ga2O3 single crystals have been grown by the floating zone technique as promising transparent conductive oxides.
