In the past 10 years, the Institute of Physics of the Chinese Academy of Sciences has used powder diffraction method to determine the crystal structure of many inorganic and organic compounds.
As one of the important means of material structure characterization, XRD is widely used in materials, physics, chemistry, medicine and other fields.
GIWAXS is a technique to characterize the internal microstructure of thin film samples. The corresponding structure size is between 10nm and 1um, so it is widely used to characterize the crystallization inside solar thin film cells.
X-ray diffractometer is a device that uses the principle of interaction between X-rays and substances to obtain information such as crystal structure and lattice constant of substances by measuring the diffraction Angle and intensity of X-rays in substances.
