## Description

- description: "Iron silicide (β-FeSi2) has attracted considerable interest as a sustainable
    thermoelectric material due to its abundance, non-toxicity, and environmental
    compatibility. Their conduction flexibility allows a wide range of dopants to
    tune transport behavior, creating opportunities for improved performance. However,
    dopant solubility limits and the formation of secondary phases remain key challenges.
    In this article, we highlight recent advances in strategies to enhance the thermoelectric
    performance of β-FeSi2-based materials and discuss the interplay between phase
    evolution, electrical, and thermal transport. We also outline prospects that may
    unlock further improvements, offering pathways toward higher thermoelectric efficiency
    in this material system.\r\n\r\nImpact Statement\r\n\r\nThis review covers the
    observation of structural transition and strategies to enhance electrical and
    thermoelectric properties of metal-doped iron silicides, providing insights for
    future research to improve material performance."
