The Pros And Cons Of Making Carbon Nanotubes

Introduction

Nanotechnology is the future of today’s world. The dictionary meaning of nanotechnology is the branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules. There is multiple types of nanotechnology like medicine, food, fuel cells, solar cells, electronics and many more. There is different materials you can use in nanotechnology in microelectronics. Carbon nanotube is one of the material used in micro technology to make carbon nanotubes transistors.

First part

Carbon is everywhere it is in even in living organisms. Carbon is a key element to life according to(). Carbon has the atomic number of 6 on the periodic table. Carbon occurs

The arce method is the method for making C60 fullerenes, this method is one of the most easiest and also most common method. The arce method creates carbon nanotubes through arc-vaporization of two carbon rods placed end to end, separated by approximately 1mm, in an enclosure that is usually filled with inert gas usually helium or argon at low pressure. Although this method is common and the eastist. The method is also great to get small and high-quality of carbon nanotubes. The arce method does have some drawbacks, The fact that it is hard to up scale the method and also the carbon nanotubes are grown in highly tangled forms. The carbon nanotubes are also mixed with other unwanted metals or other forms of carbon. The other method is chemical vapor deposition, the reaction happens in reaction tube which is also in a furnace heated to 600-900C. The reaction happens because there is a carrier/carbon source mix with an injection of catalyst as aerosol. The mixture goes into the reaction tube and forms a catalyst powder or a thin film. The structure of carbon nanotube is hexangle connection for each carbon atom. The hexangle connected carbon is folded to other side to make a cylinder. This cylinder only has a width of 0.7 to 50

The carbon is better than silicon in transistors because that the carbon nanotubes transistors consume less energy than silicon transistors. This is beneficial for increasing the life of a battery in phones. The size of carbon nanotubes are trendersly smaller than silicon. Silicon has with of 100 nanometer, but carbon nanotube has a width of only just 1 nanometer. Which makes the transistor smaller than ever before. The performance increase as well because due to the large parasitic capacitance between electrodes. array of parallel nanotubes as the transistor channel combined in a finger geometry to produce a single transistor significantly reduces the parasitic capacitance per tube and, thereby, improves high-frequency performance as stated by (www.hindawi.com). Carbon nanotubes are the next generation in world of technology due they are smaller, faster and more efficient.

Conclusion

Carbon nanotubes are better than other materials in transistors. The fact that they are smaller more efficient is great for the future in micro electronics. There is still research to be done on these carbon nanotubes definitely in transistors. Also research should be done in how to make more and efficient ways to carbon
