title: Ultrahigh thermoelectric performance by electron and phonon critical scattering in Cu2 Se1-x Ix.
abstract: 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.
