Iodine-doped Cu2 Se shows a significantly improved thermoelectric performance during phase transitions by electron and phonon critical scattering, leading to a dramatic increase in zT by a factor of 3-7 times culminating in zT values of 2.3 at 400 K.
碘掺杂的 Cu2 Se 通过电子和声子的临界散射在相变过程中表现出显著改善的热电性能，导致 zT 值增加了 3-7 倍，最终在 400 K 时达到了 2.3 的 zT 值。
