双晶

The resul,of DTA indicates that the DTA curve of Hongshuihe chert is very similar to that of standard quartz,but the DTA curve of Jingnan chert is distinct from those,i.e.there is no valley of transition heat effect at 573℃...

The X-ray double-crystal diffraction rocking curve measurements show the full-width half maximum of 180" and 185" for (0002) symmetric reflection and (10 12) skew reflection,respectively.A room temperature mobility of 850cm2/ is obtained for a 3μm thick GaN film.

Crystalline β-BBO thin films were successfully prepared on (001)-oriented Sr 2+-doped α-BBO substrates by using liquid phase epitaxy, pulsed laser deposition and vapor transport equilibration techniques. The films were characterized by X-ray diffraction and X-ray rocking curve. The present results manifest that the β-BBO thin films grown on Sr 2+-doped α-BBO substrates have larger degree of orientation f value and smaller X-ray rocking curve FWHM than the ones grown on other reported substrates.
