Figure 4
High r-region (150 Å ≤ r ≤ 200 Å) PDF curve of alumina. Experimental curve compared with the modeled curve using parameters obtained in the low r-region (see Table 2). Experimental data (circles) and modeled (solid red line). Below the curve, with displacement for easy visualization, the difference (solid green line), the main value (solid black line) and the standard deviation (dotted line) of the difference are presented. The curves were scaled according to the scale factor obtained in the PDF fitting. |
