Abstract

We discuss the electrical and photo-electrical properties of monolayers of long hydrocarbon chains (alkyltrichlorosilane molecules) self-assembled on a silicon substrate. It is shown that these monolayers (<3 nm thick) act as high quality insulators : DC conductivity through the monolayers are in the 10-15 S/cm range, energy barrier heights at the silicon/monolayer interface are in the 45 eV range. Chemical surface modifications of these monolayers are reported in order to tailor their surface as well as electrical (dielectric constant) properties. Possible sub-01 μηι device applications are presented.

15 In the calculation of the SAM thickness, we have used a value of 150 for the SAM refractive index at 633 nm for the close packed SAMs (see Refs. 13 and 14). The optical functions of the oxidized substrate have been independently determined by measuring a bare wafer cleaned by rigourously the same surface cleaning process.Google Scholar
