Electronic Current Transport through Molecular Monolayers: Comparison between Hg/Alkoxy and Alkyl Monolayer/Si(100) Junctions

Electronic current transport through alkoxy and alkyl monolayer-based junctions is presented. Monolayers are prepared on n-Si(100) with sufficiently high quality to reliably investigate the actual molecular effect of each monolayer on their current-voltage characteristics. The results show that extending the Si-binding chemistry from alkene to alcohol is feasible which should significantly facilitate preparation of monolayers with modified molecules.
