| 释义 | > as lemmasPeierls distortion 2. Used attributively with reference to a spatially periodic distortion of a linear chain of atoms or molecules in certain solids, adduced to explain an observed change from a conducting to a semiconducting or insulating state at low temperatures; esp. in Peierls distortion, Peierls transition.

Physics C 2 1093 The occurrence of Peierls doubling means that one must take into account those scattering processes in which momentum 2kf is transferred. 1973 Solid State Communications 12 1130/2 The important question is whether or not one can stabilize such a system just above the Peierls transition.., so that on lowering the temperature the superconducting state becomes truly stable. 1973 Physical Rev. B. 8 574/2 The experimental superperiod of 8 × 2·88 Å due to the platinum atoms is..in exact agreement with the expected superperiod as due to a ‘Peierls distortion’. 1989 Nature 8 June 428/3 A strong electron–phonon interaction (involving BiO bond stretching distortions) causes a textbook example of a Peierls distortion of the lattice, doubling the unit cell, splitting the conduction band in two which inhibits charge flow, and making a semiconductor. 1997 Science 28 Mar. 1896/2 Chemists have recently found a long carbon-based molecule in which the Peierls transition is absent, and thus, it can be a one-dimensional conductor. < as lemmas |
