Study on cracking and low-angle grain boundary defects in YAlO3 crystal

The structural, electrical and optical properties of spark plasma sintered BaSn1-Sb O3 ceramics

“…It also revealed the presence of Low Angle Grain Boundaries (LAGBs) between two grains oriented along [110] direction (Grain 1 and Grain 2), with the formed angle of ∼ 4.43°. In literature, LAGBs are described as series of dislocations stacked one above the other with a low tilt formed between the grains on the opposite sides of the grain boundary [45,46]. However, the grain boundaries existing between two grains oriented along different directions, [110] and [111] (Fig.…”

The temperature gradient technique (TGT) growth and optical properties of Yb-doped YAlO3 single crystal

“…3. According to the Darwinian theory [13], the theoretical FWHM value of the rocking curve of the perfect (0 1 0)-oriented YAP crystal have been calculated (FWHM ¼ 16.68 00 ) by the authors [14]. The experimental rocking curve FWHM of TGTYb:YAP crystal (65.3292 00 ) is at the same magnitude with that of the perfect YAP crystal (16.68 00 ), which means that 5 at% doped Yb:YAP crystal grown by TGT method has a good crystallization perfection.…”
