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 article, the authors investigated the transport properties of neutral, fermionic atoms passing through a one-dimensional quantum wire containing a mesoscopic lattice, which is realized by projecting individually controlled, thin optical barriers on top of a ballistic conductor.

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.
