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

Spin Excitations and Correlations in Scanning Tunneling Spectroscopy
TL;DR: In this article, perturbation theory enables one to describe the tunneling transport, reproducing the differential conductance with surprisingly high accuracy, and the emergence of correlations between spins and, in particular, between the localized spins and the supporting bath electrons are discussed.

Nanometre-cutting machine using a Stewart-platform parallel mechanism
TL;DR: In this article, a movable stage was supported with six links, each of which extends with a lever mechanism to expand the extension of a piezoelectric actuator, and the stage motion was controlled by the feedback of the link length.

Negative Differential Resistance on the Atomic Scale: Implications for Atomic Scale Devices
In-Whan Lyo,Phaedon Avouris +1 more
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.
