A vitrifying structure transition in the Dy/Mo(112) adsorption system
Annealing-driven irreversible structural transitions are studied by low energy electron diffraction in submonolayer Dy films adsorbed on the Mo(112) surface. In a wide coverage range θ > 0.07, Dy overlayers deposited at low temperatures (T≈ 100 K) are ordered and keep their structure upon anneali...
