Figure 6
X-ray 400 Bragg reflection images and RCI maps for a mounted type IIa HPHT diamond crystal with strain-relief cuts. Columns are as in Fig. 3: (a) X-ray 400 Bragg reflection images at the peak of the crystal-integrated rocking curve, (b) Bragg reflection angular widths and (c) centers of mass of the Bragg reflection angular dependences in the ROIs indicated by the red grids in column (a). Rows correspond to the following conditions: (1) after laser cutting, (2) after annealing in air at 630°C for 3 h, (3) after clamping the right-hand part in the crystal holder. |
