A two-step optimized measurement for the phase-shift
A. V. Chizhov, V. De Renzi, M. G. A. Paris
A two-step detection strategy is suggested for the precise measurement of the optical phase-shift. In the first step an unsharp, however, unbiased joint measurement of the phase an…

Oxygen adsorption on the Ru (10 bar 1 0) surface: Anomalous coverage dependence
S. Schwegmann, A. P. Seitsonen, V. De Renzi +7
Oxygen adsorption onto Ru (10 bar 1 0) results in the formation of two ordered overlayers, i.e. a c(2 times 4)-2O and a (2 times 1)pg-2O phase, which were analyzed by low-energy el…
