One-dimensional crystal growth of metal halides inside single walled carbon nanotubes

Conference item

The crystal growth behavior and crystallography of a variety of metal halides incorporated within single-wall carbon nanotubes (SWNTs) has been determined by high-resolution electron microscopy. Simple packed structures such as alkali halides form structures within SWNTs that are integral atomic layers in cross section. An enhanced HRTEM image restoration technique reveals the presence of significant lattice distortions. More complex structures formed within SWNTs, such as those derived from 3-D complex, layered and chain halides form related crystal structures within SWNTs. In narrow (i.e. 1.6nm diameter) SWNTs, these halides form structures within SWNTs that consist of individual one-dimensional polyhedral chains (1D-PHCs) derived from the corresponding bulk halides. In the case of the 3D complex and layered halide structures, the polyhedral chains form with lower coordination than in the bulk. Molecular halides also form within SWNTs but these are frequently disordered and do not readily form organized structures within SWNTs.
