โœฆ Synopsis

Atomic steps on ( ) and (100) crystal surfaces of Pt were observed using a commercial scanning electron microscope (SEMI in secondary electron mode. By comparing the SEM images and those by reflection electron microscopy (REM), the observed contrast was confirmed to be that from atomic steps on crystal surfaces. The contrast mechanism is briefly discussed. One application of this imaging technique is also shown.

t If' the analysis is to be taken seriously, we can observe that there is one jog in the almost monotonic plot of activation energy as a function of temperature. At this jog, there is a shght upward jump in the plot which is also predicted by Hart.
