Abstract
The relaxation of the electric polarization is investigated in the charge-density-wave compound Mo. Direct measurements of discharge current in the time interval of to s reveal a stretched exponential law for the time decay of polarization: , where both the initial polarization, , and the exponent () are temperature independent. The time scale of the process indicates temperature activation with an activation energy equal to the single-particle Peierls gap. The glassy relaxation of randomly pinned charge-density waves is compared with recent theories and experiments on spin-glasses.
