| Research Abstract |
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.
