Charge‐Density‐Wave Conductors

MAY 01, 1996
Low‐dimensional metals with moving lattice modulations display a host of unusual properties, including gigantic dielectric constants and the ability to ‘remember’ electrical pulse lengths.

When metals are cooled, they often undergo a phase transition to a state exhibiting a new type of order. Metals such as iron and nickel become ferromagnetic below temperatures of several hundred degrees Celsius; electron spins order to produce a net magnetization in zero field. Other metals, such as lead and aluminum, become superconductors at cryogenic temperatures; electrons form Cooper pairs of opposite spin and momentum, leading to electrical conduction with zero resistance and to expulsion of magnetic fields.
