摘要

通过使用 Atomistix 工具包进行量子输运计算，我们提出了基于碳纳米管 (CNT) 的二极管结构，该结构具有增强的二极管特性。我们的想法是使用带有氟化尖端的碳纳米管，并用绝缘（氧化锌）层将其与金属电极隔开。与由非氟化碳纳米管组成的二极管结构相比，该系统在电流大小和电流整流方面都显示出更好的工作特性。电流整流的增强与附加电压极性传输通道的形成有关。所提出的系统可用于制造基于碳纳米管的整流天线器件，从而提高太阳能转换效率。

Fluorinated carbon nanotube-insulator–metal diodes: Predictions from first-principles calculations

Using quantum transport calculations with the Atomistix Toolkit, we propose carbon nanotube (CNT)-based diode structures featuring enhanced diode properties. The idea is to use a CNT with a fluorinated tip, which is separated from the metallic electrode by an insulating (ZnO) layer. This system shows better operational properties in terms of both current magnitude and current rectification compared to diode structures consisting of non-fluorinated CNTs. The enhanced current rectification is related to the formation of additional voltage-polarity-dependent transmission channels. The proposed system can be used to create CNT-based rectenna devices with enhanced solar conversion efficiency.
