Diffusion processes on vicinally cut Ag(100) and Ag(111) surfaces have been studied utilizing the perturbed-angular-correlation (PAC) spectroscopy with 111In probes at very low concentration (10−4 ML). The occupation of step and terrace sites by PAC probes at the Ag surfaces is detected via the electric-field-gradient tensor and is observed as a function of annealing temperature. From the thermal conversion between the different 111In surface sites activation energies for microscopic diffusio...Diffusion processes on vicinally cut Ag(100) and Ag(111) surfaces have been studied utilizing the perturbed-angular-correlation (PAC) spectroscopy with 111In probes at very low concentration (10−4 ML).
