## Description

- description: "Heusler compounds with six valence electrons per atom have attracted
    interest as thermoelectric\r\nmaterials owing to their semimetallic and semiconducting
    properties. Here, we theoretically and\r\nexperimentally investigate electronic
    transport in Ru2TiSi-based full-Heuslers. We show that electronic\r\ntransport
    in this system can be well captured by a two-parabolic band model. The larger\r\nband
    gap of Ru2TiSi promises a higher thermoelectric performance, compared to its isovalent
    family\r\nmember Fe2VAl, which has been studied as a thermoelectric material for
    over two decades. Additionally,\r\nwe identify p-type Ru2TiSi as far more efficient
    than previously studied n-type compounds\r\nand demonstrate that this can be traced
    back to much lighter and more mobile holes originating\r\nfrom dispersive valence
    bands. It is predicted that the dimensionless figure of merit could exceed 1\r\nat
    around 700K if the lattice thermal conductivity of p-type compounds can be reduced,
    e.g., by\r\nsubstituting Zr or Hf for Ti."
