X-Ray Rocking Curve Characterization of SiC Substrates

WebThis scale was created by American Whitewater and uses roman numerals on a I to VI scale to indicate the level of difficulty and consequence of a rapid. There are other established systems—for example, the Grand Canyon rating system using a rating scale of 1 to 10—however, the ISRD is the most widely used. The ISRD is not an exact science. WebFrom the ensemble of images recorded along the rocking curve of our 4H-SiC sample, we produced maps of the local FWHM and peak position. These maps result, as described above, from a Gaussian ﬁt of the rocking curve recorded in each individual pixel. The FWHM map (Figure2) shows for most pixels a local FWHM that is around 60 radians.
