Time Dependence of Step Fluctuations on Vicinal Cu(1119) Surfaces Investigated by Tunneling Microscopy

Abstract

Equilibrium fluctuations of steps on vicinal Cu(1 119) surfaces show a power law time dependence.The exponent of 4 provides evidence that the step edges and the terraces do not

Step dynamics and step–step interactions on the chiral Cu(5 8 90) surface

“…A further striking result is that the surprisingly large pre-exponential factor of 10 17±2 s −1 as obtained for Cu(1 1 n) [45,46] is confirmed by the studies on Cu (5 8 90) presented here. Even if one considers the large uncertainty of Γ 0 as measured for Cu(5 8 90) the pre-exponential factor seems to be slightly larger compared to Cu(1 1 n).…”

“…Time fluctuations of steps in equilibrium are analyzed by means of a time correlation function [24,26,45,46] …”

Time dependence of step fluctuations on vicinal Cu(1 1 19) surfaces investigated by tunneling microscopy

“…Helpful discussions with N. C. Bartelt [10]. In these simulations we have assumed that the kinks advance most frequently, and therefore most eAectively by the emission of one atom at a time onto the step edge.…”

Flashlamp-pumped pulse-periodic dye lasers

“…From step correlation functions [4][5][6][7][8], e.g. one may determine the dominant mass transport mechanism which causes steps on surfaces to fluctuate in equilibrium [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Temperature variable studies may then also provide information on the activation energies involved.…”
