在亚微米尺度上研究了NbSe(3)和o-TaS(3)的电荷密度波(CDW)动力学。在足够低的温度下,在CDW滑动制度中观察到负绝对电阻区域。负电阻的起源归因于变形的CDW和准粒子感受到的不同力:CDW上的力仅仅是由电位差引起的,而准粒子电流则由电化学电位差决定。
Charge-density-wave (CDW) dynamics is studied on a submicron length scale in NbSe(3) and o-TaS(3). Regions of negative absolute resistance are observed in the CDW sliding regime at sufficiently low temperatures. The origin of the negative resistance is attributed to the different forces that the deformed CDW and quasiparticles feel: the force on the CDW is merely caused by a difference of the electric potentials, while the quasiparticle current is governed by a difference of the electrochemical potentials.
