For this concept to become reality, it will require the field of single-molecule electronics to shift towards the semiconducting platform of the current microelectronics industry. Here, we report silicon-based single-molecule contacts that are mechanically and electrically stable under ambient conditions. The single-molecule contacts are prepared on silicon electrodes using the scanning tunnelling microscopy break-junction approach using a top metallic probe. The molecular wires show remarkable current-voltage reproducibility, as compared to an open silicon/nano-gap/metal junction, with current rectification ratios exceeding 4,000 when a low-doped silicon is used. The extension of the single-molecule junction approach to a silicon substrate contributes to the next level of miniaturization of electronic components and it is anticipated it will pave the way to a new class of robust single-molecule circuits.8 p.application/pdfengcc-by (c) Aragonés, Albert C. et al., 2017http://creativecommons.org/licenses/by/3.0/esElectrònica molecularTransport d'electronsMicroscòpiaMolecular electronicsElectron transportMicroscopyinfo:eu-repo/semantics/article6730142018-04-27info:eu-repo/semantics/openAccess28406169
