High-frequency Quantum Transport

Description
These projects pursue two strategies to electrically-contact conducting molecules with devices compatible with silicon microelectronics for molecular electronics and molecular sensing. Conducting molecules embedded in self-assembled monolayers of insulating molecules are being contacted with either metal contacts for high-frequency quantum transport studies or by electrochemical solutions for capacitively-coupled molecular layers and, ultimately, single molecules.

Implications
Successfully connecting with molecules with integrated microelectronic contacts may enable interfacing with molecular electronic devices such as switches for high-density digital electronics or memories. The aqueous contacts present the possibility for biomolecular sensors for medical or security applications using mechanisms other than the more commonly used optical or electrochemical techniques.
