Figure 1

Time dependent anisotropy observed for ¹⁸¹Hf in Wurtzite GaN after implantation and RTA annealing for 120 s at temperatures indicated in the frames. The <0001> axis was aligned with the angle bisector between two detectors under 90°. The solid lines represent least squares fits to the data.

Figure 2

(a) Fraction of ¹⁸¹Hf probes in GaN showing the unique quadrupole interaction of

_Q1 = 338 MHz (open squares) after various steps of isochronal annealing programmes and the fraction associated with a defect (open triangles). (b) Width

of the frequency distribution around

_Q1 (open squares) and

_Q2 (open triangles).

Figure 3

Time dependent anisotropy observed for ¹⁸¹Hf in Wurtzite GaN after annealing for different orientations of the <0001> axis. a) aligned with the angle bisector between two detectors under 90°, b) perpendicular to the detector plane, c) aligned with one detector axis. The solid lines represent least squares fits to the data.
