Hsu, C. (author)This dissertation presents the experimental work on singlemolecule charge transport, particularly on the aspects of spin and orbital conformational effects in singlemolecule junctions. In this dissertation, we employ and develop various singlemolecule techniques, the mechanically controlled break junction (MCBJ), thermoelectric electromigrated...doctoral thesis 2022

Baum, T.Y. (author), Fernández, Saleta (author), Peña, Diego (author), van der Zant, H.S.J. (author)Polycyclic aromatic hydrocarbons radicals are organic molecules with a nonzero total magnetic moment. Here, we report on charge-transport experiments with bianthracene-based radicals using a mechanically controlled break junction technique at low temperatures (6 K). The conductance spectra demonstrate that the magnetism of the diradical is...journal article 2022

Stefani, D. (author), Weiland, Kevin J. (author), Skripnik, Maxim (author), Hsu, C. (author), Perrin, M.L. (author), Mayor, Marcel (author), Pauly, Fabian (author), van der Zant, H.S.J. (author)An appealing feature of molecular electronics is the possibility of inducing changes in the orbital structure through external stimuli. This can provide functionality on the single-molecule level that can be employed for sensing or switching purposes if the associated conductance changes are sizable upon application of the stimuli. Here, we...journal article 2018

(author), Burzuri Linares, E. (author)Embedding a magnetic electroactive molecule in a three-terminal junction allows for the fast and local electric field control of magnetic properties desirable in spintronic devices and quantum gates. Here, we provide an example of this control through the reversible and stable charging of a single all-organic neutral diradical molecule. By means...journal article 2017

(author)We report on an experimental investigation of transport through single molecules, trapped between two gold nano-electrodes fabricated with the mechanically controlled break junction (MCBJ) technique. The four molecules studied share the same core structure, namely oligo(phenylene ethynylene) (OPE3), while having different aurophilic anchoring...journal article 2015

Martin, C.A. (author), Smit, R.H.M. (author), Van Egmond, R. (author), Van der Zant, H.S.J. (author), Van Ruitenbeek, J.M. (author)We present a modular high-vacuum setup for the electrical characterization of single molecules down to liquid helium temperatures. The experimental design is based on microfabricated mechanically controllable break junctions, which offer control over the distance of two electrodes via the bending of a flexible substrate. The actuator part of the...journal article 2011

Martin, C.A. (author)During the past decades the downscaling of integrated circuits has been governed by Moore's law, which predicts device dimensions on the order of 10 nm in 2020. Fundamental research in molecular electronics explores the possibility of fabricating such nanoscale devices from single molecules, which offer the prospects of chemical tunability and...doctoral thesis 2010

Pistolesi, F. (author), Blanter, Ya.M. (author), Martin, I. (author)We study the model of a molecular switch comprised of a molecule with a soft vibrational degree of freedom coupled to metallic leads. In the presence of strong electron-ion interaction, different charge states of the molecule correspond to substantially different ionic configurations, which can lead to very slow switching between energetically...journal article 2008

(author)The high frequency mobility of charge carriers on isolated ladder-type polymer chains with lengths ranging from 13 to 54 monomer units was measured. Experiments were performed on isolated chains in dilute solution and on bulk solid samples. The ac mobility of charge carriers measured at a microwave frequency near 30 GHz is strongly dependent on...conference paper 2006

De Boer, R.W.I. (author), Klapwijk, T.M. (author), Morpurgo, A.F. (author)We report on the fabrication and electrical characterization of field-effect transistors at the surface of tetracene single crystals. We find that the mobility of these transistors reaches the room-temperature value of 0.4?cm2/V?s. The nonmonotonous temperature dependence of the mobility, its weak gate voltage dependence, as well as the...journal article 2003

(author)We have developed a technology to reproducibly make gaps with distance control on the single-atom scale. The gold contacts are flat on the nanometer scale and are fabricated on an oxidized aluminum film that serves as a gate. We show that these contacts are clean and can be stabilized via chemical functionalization. Deposition of conjugated...journal article 2003

Postma, H.W.Ch. (author)In this thesis Postma presents transport experiments performed on individual single-wall carbon nanotubes. Carbon nanotubes are molecules entirely made of carbon atoms. The electronic properties are determined by the exact symmetry of the nanotube lattice, resulting in either metallic or semiconducting behaviour. Due to their small diameter,...doctoral thesis 2001
