Article Title
Direct evidence for lip-lip interactions in multi-walled carbon nanotubes
Keywords
Multi-walled carbon nanotubes, lip lip interaction, in situ transmission electron microscopy
Abstract
The stability of open edged multi-walled carbon nanotubes has been investigated by using in situ high resolution transmission electron microscopy at elevated temperatures. Formation of inter-shell structures was experimentally observed for the first time and attributed to a robust interaction between adjacent concentric shells (so-called lip lip interaction). The fl uctuating behavior of the inter-shell structures suggests a mechanism by which the carbon atoms can pass in or out through the inter-shell edges during carbon nanotube growth or shrinkage processes.
