Binnig & Rohrer, Paper 10 (Scientific American):
|
The final paper was published in August 1985 in Scientific American.
This in itself is a measure of success. This journal, addressing
the widest possible audience for science topics, would not have
featured the STM, had it not been considered a trustworthy and newsworthy
instrument. In terms of the Nobel Prize, the timing was auspicious
too. At least one scientist will have nominated Binnig and Rohrer
before 1 February 1986, the Nobel committee deadline. The paper
itself explained the STM and floated promising applications. The
explication was done with customary clarity (cf. image on the right).

Scientific American used the phrase seeing' surfaces, which strictly
speaking is of course untrue, but the phrase is a telling measure of confidence
in the instrument). There were now three nested spring systems and eddy
current damping for the elimination of any residual vibration. The promising
applications included surface science, superconductivity, crystal structure
analysis, and friction studies. The STM might also be deployed to analyse
electronic circuitry and biological samples, such as DNA and viruses.
That is quite an impact for an instrument only 5 years old. It indicates
the extraordinary power of the STM, of course. Nonetheless, Binnig and
Rohrer might have been helped along in the negotiations within the Nobel
committee (we can only speculate until the minutes will be released after
50 years, that is in 2036) by sharing the prize with Ruschka, the main
developer of electron spectroscopy. Ruschka, Binnig, and Rohrer may have
come to represent 20th-century material samples analysis in general, and
the Nobel committee might have wanted to hurry before the 79-year old
Ruschka died. The long list of utility in the Scientific American
may also have played an important role, since Nobel's will specifies that
the prize be given for work done in the previous year (fits Binnig and
Rohrer, but not Ruschka) and that has benefited humanity the most. Arguably
electron microscopy had benefited humanity already, but STM was still
only at the prototype stage. For a thumbnail history of Scanning Probe
Microscopy up to the current day, click here.
