How does xrf measure film thickness
WebFeb 5, 2014 · Micro-XRF method of quantifying thin-film thickness and composition. Once the X-ray source (Bremsstrahlung) generates the elemental lines off the TFSC, the spectrum is then run through a thin-film quantitative routine. Typically, these routines can handle up to about five alloy layers, with about 10 elements in each layer. WebYou can find mass attenuation coefficients at NIST.gov. Assuming a limit of 1% returning photons from a silicate matrix, the depths of analysis can be approximated by the following formula: d (cm) = 4.36/ (-μ/ρ)ρ (2) where d (cm) is the depth in centimeters.
