Perrin, M.L. (author), Eelkema, R. (author), Thijssen, J.M. (author), Grozema, F.C. (author), van der Zant, H.S.J. (author)In recent years, a wide range of single-molecule devices has been realized, enabled by technological advances combined with the versatility offered by synthetic chemistry. In particular, single-molecule diodes have attracted significant attention with an ongoing effort to increase the rectification ratio between the forward and reverse...review 2020

Muthusubramanian, N. (author), Galan, E. (author), Maity, C. (author), Eelkema, R. (author), Grozema, F.C. (author), van der Zant, H.S.J. (author)We present a method to fabricate insulated gold mechanically controlled break junctions (MCBJ) by coating the metal with a thin layer of aluminum oxide using plasma enhanced atomic layer deposition. The Al<sub>2</sub>O<sub>3</sub> thickness deposited on the MCBJ devices was varied from 2 to 15 nm to test the suppression of leakage currents in...journal article 2016

Perrin, M.L. (author), Galán García, E. (author), Eelkema, R. (author), Thijssen, J.M. (author), Grozema, F.C. (author), van der Zant, H.S.J. (author)In the pursuit of down-sizing electronic components, the ultimate limit is the use of single molecules as functional devices. The first theoretical proposal of such a device, predicted more than four decades ago, is the seminal Aviram–Ratner rectifier that exploits the orbital structure of the molecule. The experimental realization of single...journal article 2016

Gorczak, N. (author), Renaud, N. (author), Galan, E. (author), Eelkema, R. (author), Siebbeles, L.D.A. (author), Grozema, F.C. (author)Quantum interference is a well-known phenomenon that dictates charge transport properties of single molecule junctions. However, reports on quantum interference in donor-bridge-acceptor molecules are scarce. This might be due to the difficulties in meeting the conditions for the presence of quantum interference in a donor-bridge-acceptor system....journal article 2016

Galán, E. (author), Perrin, M.L. (author), Lutz, M. (author), Van der Zant, H.S.J. (author), Grozema, F.C. (author), Eelkema, R. (author)We have described the synthesis of novel biphenylethane-based wires for molecular electronics. Exceptional single-molecule diode behavior was predicted for unsymmetrically substituted biphenylethane derivatives, synthesized here using the so far unexplored unsymmetrically substituted 1,2-bis(4-bromophenyl)ethanes as key intermediates, which were...journal article 2016

(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

(author)Destructive quantum interference has been shown to strongly reduce charge tunneling rates across molecular bridges. The current consensus is that destructive quantum interference occurs in cross-conjugated molecules, while linearly conjugated molecules exhibit constructive interference. Our experimental results on photoinduced charge transfer in...journal article 2015
