Considering the numerous possibilities of having suitable thermoelectric energy conversion at nano‐scale level, especially for molecular systems, in the present work we put forward a new proposal along this using a flat DNA segment as a functional element. It is modeled by coupling two chains to a form a two‐stranded ladder like geometry, with interactions to first neighbors, within the tight‐binding prescription. We critically investigate electrical and thermal properties of DNA molecule depending on the length of the system, temperature, molecule‐to‐lead coupling and the degree of (correlated) disorder. Our analysis might be helpful in analyzing thermoelectric signatures of correlated and uncorrelated disordered systems, and can be verified in laboratory.
