Figure 3
Results of a least-squares-curve fit analysis of the Se K-EXAFS data for a-Se plotted against the treatment stage (1: as-prepared; 2: under illumination; 3: after illumination; 4: after annealing at 300 K). The figures show the normalized coordination number (top) and the normalized mean-square relative displacement (bottom). The error bar indicates the range of systematic error in the normalized values evaluated from the repeated measurements. |
