Abstract
A light-emitting diode is fabricated and characterized on a semiconducting serpentine CNT which has many parallel segments with identical chirality. Compared with the individual CNT and CNT-film devices, the device with parallel segments shows improvement of an order of magnitude in current, significantly larger electroluminescent intensity, and narrower emission bands. Serpentine nanotubes are an ideal choice for practical applications of CNT-based light sources.
摘要
我们制作并分析了一个半导体蛇形碳纳米管的发光二极管，这个蛇形碳纳米管由许多具有相同手性的平行段组成。与单根碳纳米管和碳纳米管薄膜器件相比，这个具有平行段的器件的电流提高了一个数量级，电致发光强度显著增大，发射谱带变窄。对于基于碳纳米管的光源的实际应用来说，蛇形纳米管是一个理想的选择。
