Summary
Peierls Instability
is a phenomenon in
One-dimensional metallic systems
where a
Periodic lattice distortion
opens a gap at the
Fermi Surface
, resulting in a transition from a metallic to an insulating state. This instability is driven by
Electron-Phonon Interactions
and is characterized by a reduction in the electronic energy, effectively stabilizing the system into a
Lower energy state
.
