Photosensitive materials encapsulated carbon nanotubes by nanoscopically advanced plasma for nanodevice application

我们的研究表明，通过极性控制的电场可以将单链DNA分子包裹在双壁碳纳米管(DWNTs)中，并将其释放出来。研究发现，包裹的单链DNA显著改变了多壁碳纳米管的电子结构。与C_&lt；60&gt；或C_&lt；70&gt；封装的单壁/双壁碳纳米管(SWNTs/DWNTs)相比，C_&lt；59&gt；N或C_&lt；69&gt；N封装的单壁/双壁碳纳米管(SWNTs/DWNTs)表现出n型行为。根据单壁碳纳米管/硅异质结的结构，证实了单壁碳纳米管作为红外能量转换材料的可能性。与含有金属和半导体碳纳米管的原始碳纳米管相比，在碳纳米管和高纯度半导体碳纳米管中包裹C_&lt；60&gt；富勒烯可以显著提高太阳能电池的性能。

Our study demonstrates that it is possible to encapsulate and release ssDNA molecules in and out of double-walled carbon nanotubes (DWNTs)by the polarity-controlled electric field. The electronic structure of DWNTs is found to be significantly modified by the encapsulated ssDNA. C_<59> N or C_<69> N encapsulated single-walled/double walled carbon nanotubes (SWNTs/DWNTs)show the n-type behavior compared with the case of C_<60> or C_<70> encapsulated SWNTs or DWNTs. We have also confirmed the possibility of using SWNTs as the infrared energy conversion material based on the configuration of SWNT/Si heterojunction. The encapsulation of C_<60> fullerene inside SWNTs and high purity semiconductor SWNTs is found to significantly enhance the performance of solar cells compared with pristine SWNTs containing both metallic and semiconducting SWNTs.
