Binnig & Rohrer: Paper 7 (Surface Science):

Having achieved more confidence they sent off their most substantial paper yet to Surface Science (in February 1984, co-authored with Gerber and Stoll (who is Stoll?)). The purpose was to clarify the reconstruction of another gold surface, (100). Previously they had examined (110). The STM revealed a uniformly contracted and slightly rotated hexagonal top layer on top of the (100) surface. This time they compared the results with those from LEED and Auger electron spectroscopy. Their experimental set-up ensured that all methods could be applied consecutively without displacing the sample. (Exactly how?) They also did helium scattering (but probably needed to displace the sample?). They paid particular attention to the tip now, sharpening it between each picture using high electric fields. They worked in a vacuum (1.3 x 10(-8) Pa). They prepared the sample carefully by N sputtering it and annealing it at 650 degrees Celsius. Measurements were done at 50-100 degrees Celsius to keep down thermal drifts. (How was the reaction in the surface science community?)
