Indeed, since your XRD experiment is not a theta-two theta experiment but a detector scan (with a fixed grazing incidence angle), you are not able to measure any texture except if the diffraction vector stands along the texture direction which is roughly your case, by chance. I have calculated that the angle between the diffraction vector direction for the (002) diffraction peak and the normal of the sample surface is around 14¡ã (assuming a 3¡ã grazing angle). ºÜÏëÖªµÀËûÕâ14¶ÈÊÇÔõôËãµÃ£¬Äܲ»Äܸøµã ÐÅÏ¢ £¬Ð»Ð»£¡£¡£¡£¡£¡£¡£¡ |
