Fig. 75: (11L) CTR of the NiO(111) surface: () after air annealing at 1300 K, () after outgassing in UHV at 860 K and (straight line) after post oxidation at 860 K. Inset: rocking scan on the air annealed surface across the 11L CTR at L = 1.5, the width is limited by the mosaic spread of the crystal. Inset ordinate is linear.
