Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Background:

Carbon nanotubes are widely used in scanning probe microscopy.
There is a need for more rigid and easily mountable probe tips.
Controlling the structure of carbon-based nanomaterials is crucial for advanced applications.

Purpose of the Study:

To synthesize and characterize novel tubular graphite cones.
To investigate the structural properties of these graphite cones.
To evaluate their potential applications in scanning probe microscopy.

Main Methods:

Chemical vapor deposition (CVD) was employed for synthesis.
Morphological analysis was performed using microscopy techniques.
Structural characterization focused on graphite sheet chirality and arrangement.

Main Results:

Tubular graphite cones with nanometer tips and micrometer roots were successfully synthesized.
The cones possess hollow interiors with diameters from 2 to tens of nanometers.
A unique structure of continuous shortening graphite layers creates the cone shape.
Constituent graphite sheets exhibit uniform zigzag chirality, enabling structural control.

Conclusions:

The synthesized tubular graphite cones present a promising alternative to carbon nanotubes for scanning probe microscopy.
Their inherent rigidity and ease of mounting are significant advantages.
The controlled chirality offers potential for tailored tubular carbon structures.
