X-ray reflectivity
X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.
PDF X-ray thin-film measurement techniques
the X-ray reflectivity curve of a thin film deposited on a Si substrate. Therefore, the X-ray reflectivity technique is a method for determining the layer structure of a thin film. The principles of X-ray reflectivity method will be described in section 5 in greater detail. 3. Useful methods and practices in X-ray reflectivity measurement

types of x-rays, white x-rays and characteristic x-rays. White x-rays include a wide range of wavelengths and are not of interest in this experiment. Characteristic x-rays are caused by the ejection of an electron from an inner shell of an atom hit by the incident x-ray. When an outer shell electron moves to fill the space created in the inner ...
