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

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), Doelman, Matthijs (author), Eelkema, R. (author), van der Zant, H.S.J. (author)We propose the design of a single-molecule diode with a rectification ratio exceeding a million. The employed mechanism is based on coherent resonant charge transport across a molecule that consists of four conjugated sites coupled by non-conjugated bridges. Using density functional theory calculations, we rationalize the design of the...journal article 2017

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
