WebJan 21, 2012 · This gives the difference between the highest and lowest X-value that have Y-values larger than half of the maximum Y-value. That means that you will get a slightly lower value than the "width" that you ask for. If this is not acceptable, the formula can be extended to do a linear interpolation on the X-Y values near the points where Y is Max(Y)/2. WebRocking Curve. RC measurement reveals broadening of the diffraction peaks. The increase in the peak widths can be caused by: Mosaicity (misorientation of crystallites) Strain. Limited layer thickness. Typically …
WebOct 31, 2024 · The width of an emission line in this context is commonly expressed as the full width at half maximum (FWHM) and the width of an absorption line as the full width at half minimum (FWHm). (These are on no account to be confused with the equivalent width, which is discussed in section 9.1.) Note that some writers use the term “half-width”.
