Entitled “Asymmetrical Transport Distribution Function: Skewness as a Key to Enhance Thermoelectric Performance”, the article investigated the relationship between the parameters of transport distribution functions (TDFs) including location parameter, scale parameter, shape parameter and thermoelectric properties. The results showed that the asymmetry of TDF, characterized by skewness, is a more general and universal parameter to capture the trend of thermoelectric power, power factor as well as the dimensionless thermoelectric figure of merit (ZT). The author also proposed a novel skewness, called thermoelectric skewness, which is demonstrated to not only perfectly capture the main feature of conventional skewness but also predict accurately the thermoelectric power by comparing it with ab initio calculations and experiments. This comparison confirms the unique feature of the new proposed thermoelectric skewness, as well as its special role in the connection between the statistics of TDF and thermoelectric properties of materials.
