    Vibron-assisted spin excitation in a magnetically anisotropic molecule

    The electrical control and readout of molecular spin states are key for high-density storage. Expectations are that electrically-driven spin and vibrational excitations in a molecule should give rise to new co...

    Protection of excited spin states by a superconducting energy gap

    When a paramagnetic molecule is placed on a superconducting surface the lifetime of its spin excitations increases dramatically. This effect, caused by the depletion of the electronic states within the energy ...

    Charged and metallic molecular monolayers through surface-induced aromatic stabilization

    Large π-conjugated molecules, when in contact with a metal surface, usually retain a finite electronic gap and, in this sense, stay semiconducting. In some cases, however, the metallic character of the underlying...

    Formation of extended straight molecular chains by pairing of thymine molecules on the Ag–Si(111) surface

    Here, we report on the assembly of thymine molecules into extended straight chains of single and multiple dimer rows on a Si(111)/Ag $\sqrt{3}...

    Trans to cis isomerization of an azobenzene derivative on a Cu(100) surface

    This article reports the observation of two stable configurations of an azobenzene derivative on a Cu(100) surface, which resemble the trans and the cis isomers of the free molecule. Whereas the trans form is the...

    Single molecule vibrationally mediated chemistry

    Tunnelling electrons may scatter inelastically with an adsorbate, releasing part of their energy through the excitation of molecular vibrations. The resolution of inelastic processes with a low temperature sca...

    Selectivity in vibrationally mediated single-molecule chemistry

    The selective excitation of molecular vibrations provides a means to directly influence the speed and outcome of chemical reactions. Such mode-selective chemistry1 has traditionally used laser pulses to prepare r...

    Study of Contact in the Fabrication of Gold Nanostructures by Scanning Tunneling Microscopy

    Gold nanostructures deposited in an STM configuration by voltage pulsing are produced by mechanical contact between tip and sample. The contact resistance shows discrete jumps which are indicative of atomic re...
