Shot noise and magnetism of Pt atomic chains: accumulation of points at the boundary
Manohar Kumar, Oren Tal, Roel H. M. Smit +3
Pt is known to show spontaneous formation of monatomic chains upon breaking a metallic contact. From model calculations, these chains are expected to be spin polarized. However, di…
Electronic inhomogeneities in graphene: the role of the substrate interaction and chemical doping
A. Castellanos-Gomez, Arramel, M. Wojtaszek +5
We probe the local inhomogeneities of the electronic properties of graphene at the nanoscale using scanning probe microscopy techniques. First, we focus on the study of the electro…
Spatially resolved electronic inhomogeneities of graphene due to subsurface charges
Andres Castellanos-Gomez, Roel H. M. Smit, Nicolás Agraït +1
We probe the local inhomogeneities in the electronic properties of exfoliated graphene due to the presence of charged impurities in the SiO2 substrate using a combined scanning tun…
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…
Metallic properties of magnesium point contacts
R. H. M. Smit, A. I. Mares, M. Haefner +3
We present an experimental and theoretical study of the conductance and stability of Mg atomic-sized contacts. Using Mechanically Controllable Break Junctions (MCBJ), we have obser…
