TLDR
In this paper, Binnig and Rohrer used the scanning tunnelling microscope (STM) to position individual xenon atoms on a single-crystal nickel surface with atomic pre-cision.Abstract:
SINCE its invention in the early 1980s by Binnig and Rohrer1,2, the scanning tunnelling microscope (STM) has provided images of surfaces and adsorbed atoms and molecules with unprecedented resolution The STM has also been used to modify surfaces, for example by locally pinning molecules to a surface3 and by transfer of an atom from the STM tip to the surface4 Here we report the use of the STM at low temperatures (4 K) to position individual xenon atoms on a single-crystal nickel surface with atomic pre-cision This capacity has allowed us to fabricate rudimentary structures of our own design, atom by atom The processes we describe are in principle applicable to molecules also In view of the device-like characteristics reported for single atoms on surfaces5,6, the possibilities for perhaps the ultimate in device miniaturization are evidentread more

TL;DR: In this paper, the conformations of organometallic polymers formed via bottom-up assembly of monomer units on a metal surface are investigated, and the relationship between the adsorption geometry of the individual polymers, the conformational structure of the chain and the overall shape of the polymer is explored.

Reversible rotation of antimony dimers on the silicon (001) surface with a scanning tunneling microscope.
TL;DR: The scanning tunneling microscope (STM) tip induced a reversible rotation between two orthogonal orientations of individual antimony dimers on the surface of silicon, which could provide a basis for making atomic-scale memory cells.

Au dimers on thin MgO(001) films: flat and charged or upright and neutral?
Violeta Simic-Milosevic,Markus Heyde,Niklas Nilius,Thomas König,Hans-Peter Rust,Martin Sterrer,Thomas Risse,Hans-Joachim Freund,Livia Giordano,Gianfranco Pacchioni +9 more
TL;DR: A combination of low temperature scanning tunneling microscopy (STM) and theoretical calculations is used to investigate Au dimers, supported on thin MgO(001) films, whose thickness was chosen such that charge transfer from the Ag substrate to the deposited Au is possible.

Molecular manipulation using a tunnelling microscope
TL;DR: The accomplishment of the smallest yet, purposeful, spatially localized changes in matter, effected on a graphite surface is reported, believing that the changes result from the pinning of individual organic molecules to the graphite.
