Incorporating Molecular Monolayers into Electronic Devices

Adina Scott of Purdue University explores recent interest into incorporating molecular monolayers into electronic devices for sensing, nanoelectronic, energy conversion and biological applications. Device properties can be modulated using surface chemistry, leading to flexible fabrication schemes and new system functionalities.

Examine key challenges related to the fabrication, structural characterization and electrical properties of such systems. Look at results for metal-molecule-silicon devices in which the electronic transport is governed by the interplay between the molecular-electronic properties and silicon bandstructure, enabling novel hybrid organic/semiconductor functionality.

Combining these device concepts with optically-, biologically- or electrically-active molecular layers will result in new classes of hybrid devices with the potential for low-cost, highly-integrated systems.
