Here, the electric and thermoelectric transport coefficients of nanocomposites are investigated using the Non‐Equilibrium Green's Function (NEGF) method, which can accurately capture the details of geometry and disorder in these structures. Two‐dimensional (2D) channels with embedded nanoinclusions (NIs) are considered, which are modelled as potential barriers of cylindrical shape and heightV  B    . The effect of randomness of the NIs on the thermoelectric power factor is investigated by varying the positions, diameter, and heights of the barriers according to a Gaussian probability distribution. It is found that the power factor shows indications of tolerance to variations in the parameters of the NIs when the Fermi level is placed into the bands andV  B   ∼   k  B   T   . These results could be experimentally relevant in the design of nanocomposites for thermoelectric applications.
