Abstract: The thermoelectric properties of a molecular chain composed of oligothiophene attached to gold electrodes are investigated using the first-principles approach combined with Green function formalism in the linear response regime. Results show that the electrical conductance decays exponentially with the length of the molecular chain, whereas the thermopower linearly increases. In addition, it is observed that as the temperature increases, the increase in the molecular chain length results in the reduction of the electrical conductance and an increase in the thermopower. It is also examined how the thermoelectric efficiency of the molecular junction can be improved by adjusting the Fermi level of the electrodes and temperature.
