Importance of the Problem:

This project examines quantum functional devices in the conjugated polymer system for molecular electronic devices and circuits. These enhanced circuits are aimed to be more energy thrifty than conevtional transistor-only circuits and facilitate high-speed operation to reach node-to-node iwireless communication.

Brief Description of Our Work and Results:

Conjugated polymers, with pi molecular orbitals delocalized along the polymer chain, are useful organic semiconductors that provide the possibility of molecular electronics for low power organic-based memory and logic. Quantum functional devices based upon carrier tunneling processes open vistas into very efficient and low power consumption circuitry that would be ideal for these applications.

We demonstrate here strong room temperature NDR for poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylenevinylene] (MEH-PPV) polymer tunnel diodes using a thin TiO2 tunneling layer (~2-8 nm) sandwiched between the MEH-PPV and the indium tin oxide anode.

A key advantage is the pronounced NDR using a thick polymer layer with a large active area, circumnavigating the need for molecularly sized junctions. Current-voltage measurements show large and reproducible NDR with a PVCR as high as 53 at room temperature. We also demonstrate basic logic circuit operation using a pair of these polymer tunnel diodes connected in series to form a monostable-bistable transition logic element latch. Our results indicate that polymer tunnel diodes are potential candidates for many flexible, low-power logic and memory applications for organic devices by using low-cost and simple solution processing.
