(abstract)

Tin mono-selenide (SnSe) is one of the high-performance thermoelectric materials, and recent progress has been made in its application to thin-film thermoelectric devices. However, the performance of SnSe polycrystalline and epitaxial films has been limited by their electronic conductivity lower than the single crystal due to strong carrier scattering. In this paper, we investigated the origin of carrier scattering through nanoscale characterization of a-axis oriented SnSe films with different grain boundary (GB) structures (i.e., a-axis misorientations and in-plane rotational GBs).
