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.
