WebbA Peierls transition or Peierls distortion is a distortion of the periodic lattice of a one-dimensional crystal. Atomic positions oscillate, so that the perfect order of the 1D crystal is broken. 1 Rudolf Peierls discovered it in the 1930’s when writing a section on one-dimensional models in an introductory solid-state textbook.
