## Title

- title: Nanoscale Origin of Strong Charge Carrier Scattering at Grain Boundaries
    in Orthorhombic SnSe Semiconductor Thin Films
  title_type: original
  lang: en

## Description

- description: 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).
