Binnig & Rohrer, Paper 5 (Surface Science Letters):

Gerber and Weibel were back on board as co-authors of a paper sent to Surface Science Letters in April 1983. (What was the difference in status and turn-around time of Surface Science and its Letters?) The paper acknowledged A. Baratoff, a theoretical physicist who was one of the first to publish on STM theory. Baratoff also worked at IBM Zurich.

STM scans of Au(110) surfaces revealed (111) facetting and 1x2 structure, with some local disorder. [Au(110) rough (top) and Au(110) fine (botton)] They compared the results with transmission electron micrscopy and glancing angle x-ray diffraction. They suggested that the local disorder might be the reason that averaging techniques, such as diffraction, had not yet delivered conclusive evidence on a topic of interest, the transition time from 1x1 to 1x2 structure. Of course, this amounted also to an argument for the comparative prowess of the STM. Queries: why were the technicians back on board: did they set up the TEM and x-ray diffraction? What sort of questions were scientists asking at the time, and how did this paper affect them?
