The crystalline perfection and homogeneity of the DyScO3 and GdScO3 single crystals are characterized by a full-width at half-maximum of the 220 reflection of the substrates of about 20 25 arcsec in ω and a very small fluctuation margin of about ±3 arcsec over the whole wafer surface.
In an economy with 147 million workers, the margin of error in measuring fluctuations of 100,000 or 200,000 jobs is enormous and the numbers themselves are extremely volatile.
