XRD and XPS characterization of typical samples investigated. a X-ray rocking curves for MCT-based structure: 1 initial, 2 boron implanted, and 3 annealed. b X-ray rocking curves for MCT-based structure: 1 initial, 2 silver implanted, and 3 annealed. c XPS survey spectrum of MCT-based structure after silver ion bombardment and annealing. d GI XRD spectrum of MCT-based structure after silver ion bombardment and annealing. Inset shows the X-ray diffraction spectrum of the sample in the Bragg configuration
