Thermoelectric properties of molecular nanostructures
We use the concept of resonant tunneling to calculate the thermopower of molecular nanosystems. It turns out that the sign of the thermovoltage under resonant tunneling conditions depends sensitively on the participating molecular orbital, and one finds a sign change when the transport channel switc...

| description | We use the concept of resonant tunneling to calculate the thermopower of
molecular nanosystems. It turns out that the sign of the thermovoltage under
resonant tunneling conditions depends sensitively on the participating
molecular orbital, and one finds a sign change when the transport channel
switches from the highest occupied molecular orbital to the lowest unoccupied
molecular orbital. Comparing our results to recent experimental data obtained
for a BDT molecule contacted with an STM tip, we observe good agreement. |
