What Does PEGC Stand For?

PEGC stands for Phonon Glass Electron Crystal

PEGC, or Phonon Glass Electron Crystal, refers to a class of materials that exhibit distinct properties for phonons (vibrational energy quanta) and electrons. In PEGC materials, phonons are scattered and lose their coherence, allowing for poor thermal conductivity, while electrons maintain high mobility and conductivity. This unique combination facilitates advanced applications in thermoelectrics, where efficient temperature gradient conversion to electrical energy is desired. PEGC materials are of significant interest in enhancing energy efficiency and developing new technologies for thermal management.
