The prefix "nano" implies that the diameter of the 1D structure is in the nanometer regime, rather than larger than a micrometer. The term "fiber" implies nothing specific about the structure of the fiber - it may be a single crystal, crystallographically amorphous (like conventional glass is), polycrystalline, etc. The term "whisker" is generally accepted to mean that the 1D structure is a single crystal, or at least approaches single-crystal character fairly closely. "Tube" of course implies a hollow center. "Nanowire" is perhaps the most troublesome. To some of us the term "nanowire" implies that the electrical-transport measurements have been made, and the 1D structures have been found to be either semiconductors or metallic conductors. To others, the term "nanowire" is used in much the same way as "nanofiber." So you can see, standard definitions have not yet been fully developed. Nanotubes may also be considered to be "nanowires." Nanowires must not necessarily be fully dense as our's are; they could be hollow |
