  • Abstract
    GeTe is a conducting ferroelectric with a very simple crystal lattice. Since decades, its phase transition was deemed displacive; recent evidence suggested an order-disorder type. High-temperature THz spectra of thin films reveal a new sub-THz excitation but no critical phonon softening is observed.
