Abstract
The novel technique of linearly heating a sample to obtain both the pr e-exponential factor D-0 and the activation energy E from a single run is applied to the Cu(111)(Sn,S) system. Using Auger electron spectros copy the surface enrichment is measured as a function of time (tempera ture) and fitted with an integral expression containing the fit parame ters D-0 and E. The fit values at all heating rates agree excellently with published, our own experimental and conventional t(1/2) values af ter temperature corrections.
