本文研究了准一维导体$o$-TaS$_3$的非局域输运。电荷密度波中的电输运现象包括热激发准粒子和电荷密度波的集体运动。尽管它的长程相关性，集体运动的CDW不延伸远远超出电极，相位滑移打破了相关性。我们发现，非局域电压出现在CDW的$0 $-TaS$_3$，低于和高于CDW滑动的阈值场。的非局域电压的温度依赖性表明，所观察到的非局域电压起源于CDW甚至低于阈值场。此外，我们在钉扎和滑动状态的非局部电压的观察揭示了一个载体的存在与远程相关，除了滑动CDW和热激发准粒子。
We studied the nonlocal transport of a quasi-one dimensional conductor $o$-TaS$_3$. Electric transport phenomena in charge density waves include the thermally-excited quasiparticles, and collective motion of charge density waves (CDW). In spite of its long-range correlation, the collective motion of a CDW does not extend far beyond the electrodes, where phase slippage breaks the correlation. We found that nonlocal voltages appeared in the CDW of $o$-TaS$_3$, both below and above the threshold field for CDW sliding. The temperature dependence of the nonlocal voltage suggests that the observed nonlocal voltage originates from the CDW even below the threshold field. Moreover, our observation of nonlocal voltages in both the pinned and sliding states reveals the existence of a carrier with long-range correlation, in addition to sliding CDWs and thermally-excited quasiparticles.
