Investigation of Novel Self-Assembled Nano-Electronics - Towards Tunable Quantum-Mechanical Resonance

Specially designed functional molecules are the next logical step in the ongoing miniaturization of mechanical, electronic, and opto-electronic devices. The present proposal responds to the necessity of systematic theoretical investigations of interfacial properties of electrode/molecule junctions. The main scientific objective of the proposed project is to outline a novel approach toward molecular electronic devices. Our intention is to induce strong electronic coupling of charge-transfer character between noble-metal contacts and covalently attached (self-assembled) molecules, thus integrating molecules and equally nanoscopic metal contacts into one functional unit. This goal is to be achieved by tuning both the molecules and the type, size, and dimensionality of the metal contacts in order to line up the metal Fermi energy with the frontier molecular orbitals and induce quantum-mechanical resonance between the two electronic subsystems. The core part of this multidisciplinary, joint theoretical and experimental proposal will be the applicant s computational work. Complimentary scientific training will consist of participating in these experiments.
