Note: The first fullerene discovered was Bucky Ball;   The most properties that are expressed about fullerenes are related to these two types C70 and C60 .

Fullerenes are nanometer-sized molecules that, in their simplest form,  form 60 carbon atoms of a graphite layer with a three-dimensional structure.  60 Unlike diamond and graphite, whose molecules are continuous, fullerenes are closed molecules: they are like C60 and... (60) fullerenes, which are also called buckyball and buckytube, include nanotubes, nanofibers, fullerene has a structure similar to graphite, but instead of completely hexagonal sections, carbon atoms  are placed in the vertices of the 5th or 7th polygons. 


There are two types of connections in the structure of diamond nanographites:

1-  Covalent bond, the connection between the carbon atoms of each honeycomb layer.

2-  It is a connection that connects the layers of the honeycomb. 

Nano graphite, like honeycomb plates, has high strength due to having a strong covalent bond; On the contrary, this structure is much less strong than the honeycomb panels. The structure of diamond nanographite has a lattice structure. In nano-graphite, atomic bonds are established only on the surface, while in the diamond structure, these bonds fill the space in a three-dimensional network. In graphite, the carbon atom forms a covalent bond with three other carbon atoms, while in diamond, the carbon atom forms a covalent bond with four other carbon atoms.

Applications of nano diamond in nano electronics industries 

in nanoelectronic industries; Nano chip, increasing the speed of nano transistors, both types of diamonds, i.e. n and p type stones, are used for nanoelectronic applications in microelectronics. He produced blue diamonds and by adding phosphorus to colorless diamonds, he also produced n-type diamonds. Today, many semiconductors such as silicon are used in a wide range of nanoelectronic devices. However, due to the range of thermal changes and its extremely high speed, nano diamond is only compared to gold nanoparticles, which holds the title of the second best nano semiconductor in the world.

Conclusion : 

Nano graphite and graphene nano strips are electrically conductive due to cloud scattering. Active nano diamond particles with such features, especially electronic ones, can be the foundation of completely new types of powerful nano electronic devices.
