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

Temporal behaviour of nanofeatures on Au
TL;DR: In this article, a tip-crash technique was used to write dents of 5-10 nm dimension with a W tip on bulk Au, which subsequently decay as a result of surface diffusion of Au atoms.

Nanomanipulation of single DNA molecules and its applications
TL;DR: In this article, the results of a cooperation between the Shanghai joint group and the University of Saarland on the manipulation of single DNA molecules and some possible applications based on single molecule manipulation and structural characterization are discussed.

TL;DR: An enhancement of the SPM technique is reported that makes the manipulation of large molecular adsorbates much more effective and writes a nanoscale structure in a monolayer of large molecules, thereby showing that the method allows for the successful execution of complex manipulation protocols even when the potential energy surface that governs the interaction behaviour of the manipulated nanoscales object(s) is largely unknown.

Assembling and disassembling Ag clusters on Si(111)-(7×7) by vertical atomic manipulation.
TL;DR: This work has demonstrated a vertical manipulation technique to reproducibly and reversibly manipulating Ag atoms on an Si(111)-(7×7) surface by a scanning tunneling microscope tip at room temperature, which can form a fundamental basis for further studies of the Ag/Si(111-(7–7) system and for fabricating functional nanodevices in various metal-semiconductor systems.

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.
