What is the Barrier for Tunneling Through Alkyl Monolayers? Results from n‐ and p‐Si–Alkyl/Hg Junctions

Abstract

By combining experimental electron-transport results through an alkane monolayer sandwiched between Si and a metal, photoemission data from the monolayer-on-Si, and theoretical calculations, we show that transport is dominated by a distribution of mixed Si molecular levels, rather than a single molecular level, as shown schematically in the figure.
