Conductance measurements of a molecular wire, contacted between an epitaxial molecule–
metal bond and the tip of a scanning tunnelling microscope, are reported. Controlled …

Molecular electronics offers unique scientific and technological possibilities, resulting from
both the nanometre scale of the devices and their reproducible chemical complexity. Two …

The electronic spectrum of a chemically contacted molecule in the junction of a scanning
tunneling microscope can be modified by tip retraction. We analyze this effect by a …

Advances in molecular electronics depend on the ability to control the charge and spin of
single molecules at the interface with a metal. Here we show that bonding of metal–organic …

As the dimensions of a conductor approach the nanoscale, quantum effects begin to
dominate, and it becomes possible to control the conductance through direct manipulation of …

Single-molecule spintronics investigates electron transport through magnetic molecules that
have an internal spin degree of freedom. To understand and control these individual …

The Kondo effect observed in recent scanning tunneling microscopy (STM) experiments on
transport through CoPc and TBrPP-Co molecules adsorbed on Au (111) and Cu (111) …

We investigate minimal molecular junction models to account for zero-bias anomaly and the
inelastic transport by discrete molecular phonons. Nonlinear transport calculations with the …

A low-temperature scanning tunneling microscope is employed to build a junction
comprising a Co atom bridging a copper-coated tip and a Cu (100) surface. An Abrikosov …

Transport through molecular magnets is studied in the regime of strong coupling to the
leads. We consider a resonant-tunneling model where the electron spin in a quantum dot or …
