在无序聚（N-乙烯基咔唑）（PVK）中观察到非色散跳跃输运，但在相关聚合物3 Br-PVK中没有观察到。结果表明，跳跃时间分布ψ（t）t-（1+ α）可以解释有限温度范围内的渡越时间色散，但需要更复杂的ψ（t）来模拟更广泛温度范围内的结果。样品形态和瞬态色散之间的微妙关系被证明。
Nondispersive hopping transport has been observed in disordered poly (N-vinylcarbazole)(PVK) but not in the related polymer 3 Br-PVK. The results demonstrate that a hopping-time distribution ψ (t)∼ t−(1+ α) can account for the transit-time dispersion in a limited temperature range but that more complicated ψ (t)'s are necessary to model the results in a broader temperature range. The subtle relation between sample morphology and transient dispersion is demonstrated.
