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

Two-dimensional lattice of out-of-plane dinuclear iron centers exhibiting Kondo resonance.
TL;DR: Investigation of two-dimensional coordination networks formed by 5,10,15,20-tetra(4-pyridyl)porphyrin and iron atoms on a Au(111) surface shows evidence that the network structure is stabilized by a coordination motif in which a pair of vertically aligned Fe atoms is ligated by four equatorial pyridsyl groups.

Review: recent advances and current challenges in scanning probe microscopy of biomolecular surfaces and interfaces.
TL;DR: There are a growing number of studies in which SPM has been successfully used to achieve subnanometer resolution measurements in biological systems where carefully designed and prepared samples have been paired with appropriate SPM techniques.

Surface studies by scanning tunneling microscopy
TL;DR: In this paper, surface microscopy using vacuum tunneling has been demonstrated for the first time, and topographic pictures of surfaces on an atomic scale have been obtained for CaIrSn 4 and Au.

Tunneling through a controllable vacuum gap
TL;DR: In this article, the first successful tunneling experiment with an externally and reproducibly adjustable vacuum gap is reported, based on the exponential dependence of the tunneling resistance on the width of the gap.

TL;DR: scanning tunneling microscopy and scanning tunneling spectroscopy are shown that the current-voltage characteristics of a diode configuration consisting of an STM tip over specific sites of a boron-exposed silicon(111) surface exhibit NDR.

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.
