Influence of chemical structure on the stability and the conductance of porphyrin single-molecule junctions
Mickael L. Perrin, Ferry Prins, Christian A. Martin +9
Porphyrin molecules can form stable single molecule junctions without anchoring groups. Adding thiol end groups and pyridine axial groups yields more stable junctions with an incre…
Surprising lack of magnetism in the conductance channels of Pt atomic chains
Manohar Kumar, Oren Tal, Roel H. M. Smit +1
Pt is known to show spontaneous formation of chains of metal atoms upon breaking a metallic contact. From model calculations these have been predicted to be spin polarized, which i…
Transition Voltage Spectroscopy and the Nature of Vacuum Tunneling
M. L. Trouwborst, C. A. Martin, R. H. M. Smit +4
Transition Voltage Spectroscopy (TVS) has been proposed as a tool to analyze charge transport through molecular junctions. We extend TVS to Au-vacuum-Au junctions and study the dis…
