Definition of Peierls in English: Peierlsnoun ˈpʌɪəːlz Physics 1Used attributive with reference to the resistance to the movement of a dislocation along a slip plane arising from the periodic nature of the crystal lattice, as "Peierls barrier", "Peierls force", "Peierls potential", "Peierls stress". 2Used attributive 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; especially in "Peierls distortion", "Peierls transition".
Origin 1950s. From the name of Sir Rudolf Peierls, German-born British physicist, who described the distortion in Quantum Theory of Solids 108.
