The ability of a thermoelectric material to be used for electric generators is measured through its thermoelectric figure of merit (ZT) which is directly related to the device efficiency. Figure of merit of a material is dependent on three transport quantities, electrical conductivity (&#963;), Seebeck coefficient or thermoelectric power (S), and thermal conductivity which comes from lattice vibration (&#954;ph) and charge carriers (&#954;e). The three transport quantities is being calculated through Boltzmann <br /> <br /> Transport Theory using two assumption, linearisation of perturbation, and the relaxation time approximation (RTA). Investigation of transport properties is being made for Dirac materials, which is a new material classification, notably for its unique effective carrier behaviour in the vicinity of Fermi energy, compared to the standard materials. Considering only the single band E > 0, for both case of Dirac materials, the gapless and gapped energy, the obtained ZT values can be higher than the reference semiconductor case, or even the maximum value of current <br /> <br /> thermoelectric materials which is about 1. In extreme cases, its value even become significantly large and non-saturating for &#945; = 0. Here, two physical quantities have <br /> <br /> <br /> to be met to achieve the preferred zT value, the phonon thermal conductivity and a range of temperature.
