Graphene, the single layer of hexagonally coordinated carbon, is a two-dimensional material with many unusual properties; its physical realization a few years ago has caused a storm of activities in the solid state physics and materials science commu

In copper-oxide superconductors, charge carriers must be added to the insulating ‘parent’ compound before superconductivity appears. Exactly how the dopants affect the crystalline surface and evolving Fermi surface is now clear.

In recent years, it has become possible to create well-ordered semiconductor surfaces with metallic surface states by using self-assembly of metal atoms. Since these states lie in the band gap of the semiconductor, they completely decouple from the s

A self-assembled monolayer of ferrocene-capped alkanethiols is produced in two stable oxidation states of Fe (Fe2+ and Fe3+). These oxidation states are detected with sub-monolayer sensitivity by the fine structure of the Fe2p absorption edge. The na

It is shown how atomically precise step arrays can be fabricated on vicinal Si(111). Decoration with metal atoms produces atomic chains that serve as the ultimate nanowires for the study of electrons between one and two dimensions. Chain structures a

Scanning tunneling microscopy images of the Si(1 1 1)5×2–Au surfaces exhibit irregularly distributed protrusions of atomic size. They are identified as silicon adatoms by evaporating small amounts of silicon and gold onto the reconstructed surface

A one-dimensional 5 � 2 reconstruction of Gd is observed on Si(1 1 1), which can be stabilized in single domain form on vicinal surfaces. It contains zig-zag rows of occupied orbitals alternating with rows of unoccupied orbitals, as inferred from s

One-dimensional electron systems can now be synthesized at stepped surfaces by self-assembly of atomic and molecular chains. A wide variety of adsorbate and substrate combinations provides opportunities for systematically tailoring electronic propert

The pathway for thermal decomposition of an oleic acid surfactant protecting Co and Ni nanocrystals is identified by probing the relevant molecular orbitals with x-ray absorption spectroscopy. The two steps observed previously in thermogravimetric me

Self-assembled electronic devices, such as quantum dots or switchable molecules, need self-assembled nanowires as connections. We explore the growth of conducting Gd disilicide nanowires at step arrays on Si(111). Atomically smooth wires with large a
