Ultrathin, sputter-deposited, amorphous alloy films of ruthenium and molybdenum

Autor: Yetik, G., Troglia, A., Farokhipoor, S., van Vliet, S., Momand, J., Kooi, B. J., Bliem, R., Frenken, J. W. M.

Publikováno v: Surface and Coatings Technology, Volume 445, 15 September 2022, 128729

Microscopy and diffraction measurements are presented of ultrathin binary alloy films of ruthenium and molybdenum that are obtained by standard sputter deposition. For compositions close to Ru50Mo50, we find the films to be amorphous. The amorphicity

Superlubric to stick-slip sliding of incommensurate graphene flakes on graphite

Autor: van Wijk, M. M., Dienwiebel, M., Frenken, J. W. M., Fasolino, A.

Publikováno v: Phys. Rev. B 88, 235423 (2013)

We calculate the friction of fully mobile graphene flakes sliding on graphite. For incommensurately stacked flakes, we find a sudden and reversible increase in friction with load, in agreement with experimental observations. The transition from smoot

Evidence for contact delocalization in atomic scale friction

Autor: Abel, D., Krylov, S. Yu., Frenken, J. W. M.

We analyze an advanced two-spring model with an ultra-low effective tip mass to predict nontrivial and physically rich 'fine structure' in the atomic stick-slip motion in Friction Force Microscopy (FFM) experiments. We demonstrate that this fine stru

Vacancy diffusion in the Cu(001) surface I: An STM study

Autor: van Gastel, R., Somfai, E., van Albada, S. B., van Saarloos, W., Frenken, J. W. M.

Publikováno v: Surf. Sci. 521, 10 (2002)

We have used the indium/copper surface alloy to study the dynamics of surface vacancies on the Cu(001) surface. Individual indium atoms that are embedded within the first layer of the crystal, are used as probes to detect the rapid diffusion of surfa

Vacancy diffusion in the Cu(001) surface II: Random walk theory

Autor: Somfai, E., van Gastel, R., van Albada, S. B., van Saarloos, W., Frenken, J. W. M.

Publikováno v: Surf. Sci. 521, 26 (2002)

We develop a version of the vacancy mediated tracer diffusion model, which follows the properties of the physical system of In atoms diffusing within the top layer of Cu(001) terraces. This model differs from the classical tracer diffusion problem in

Nothing moves a surface: vacancy mediated surface diffusion

Autor: van Gastel, R., Somfai, E., van Albada, S. B., van Saarloos, W., Frenken, J. W. M.

Publikováno v: Phys. Rev. Lett. 86, 1562 (2001)

We report scanning tunneling microscopy observations, which imply that all atoms in a close-packed copper surface move frequently, even at room temperature. Using a low density of embedded indium `tracer' atoms, we visualize the diffusive motion of s
