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

Behavior of a Magnetic Impurity in Graphene in the Presence of a Vacancy
TL;DR: In this paper, the authors investigated the consequences of placing a magnetic adatom adjacent to a vacancy in a graphene sheet and found that the behavior of the adatom in the presence of a vacancy differs significantly from its behavior in the absence of a vacant state.

TL;DR: In this article, the authors used atomic manipulation and scanning tunneling spectroscopy to study the evolution in electronic properties that occurs as two Ni atoms are merged into a single magnetic molecule on Au(111) and observed energetic shifting of molecular d-orbitals and a strong decrease in the molecular Kondo temperature as Ni-Ni separation is reduced to 3.4+ or -0.3Angstroms.

Single-step electrochemical nanolithography of metal thin films by localized etching with an AFM tip
TL;DR: It is demonstrated that Cu films as well as Co and Cu/Co sandwich magnetic films can be patterned if negative voltage pulses are applied to the tip, and the lateral dimension of lithographed structures is tunable, from a few micrometers down to 150 nm, by appropriate choice of ENL conditions.

Tunnelling junctions with additional degrees of freedom: An extended toolbox of scanning probe microscopy
Christian Wagner,Ruslan Temirov +1 more
TL;DR: In this paper, a view is presented according to which the tip decoration generally introduces additional degrees of freedom into the scanning junction and thus extends its functionality, in particular tips decorated with atomic point-like particles may attain the additional function of a force sensor.

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.
