Length enhancement of thermoelectric effects in DNA duplex chains due to quantum interferences

(a) The schematic illustration of the DNA ladder model, (b) the up limit of ZT maxima (square) and the corresponding energies (circle) versus the number n of (T:A) base pairs. Due to the large value of ZT, DNA duplex chains, as a very excellent candidate material, could be used in high performance thermoelectric devices.124
