Bond-strength engineering beyond mass fluctuation: unraveling the dominant mechanism of lattice thermal conductivity suppression in neighboring-site doped β-FeSi<sub>2</sub> thermoelectrics
In addition to the atomic mass/size difference between Ir and Fe, the imbalance in chemical bonding caused by Co doping at the adjacent site can lead to a significant reduction in the lattice thermal conductivity of β-FeSi 2 .
