Scientific researchers have finally discovered a new way that they can grow carbon nonotube semiconductors after years of detailed research. They can do this by defining it to particular distinct structure. This has a great potential of carbon being an essential element used in development of electronics in the near future. An outstanding fact about this research is that it paves way for carbon as an effective substitute to silicon. Based on the fact that silicon has been central in this industry since the advent of the computing era. This is way back in the 1960′s when technology was picking up. This is reason why the technological hub was called- Silicon Valley.
It is an undisputed fact that scientist and leading industry professionals have agreed on; in the near future carbon nanotube will finally replace silicon. This is due to the many advantages that it has over its counterpart. The transistors that have been made from nanotube are smaller in size, their power consumption is relatively low, and are much faster. However, the technical challenges associated with the manufacturing process have hindered mass production of nanotube. The several aspects you should understand are that controlling the diameter and chirality is quite hard. Another equally important character that posse a great challenge is to get a definite size.
To define chilarity in simple terms and practically; take a paper and slowly insert it into a tube of any length, the new properties it takes that define its shape are its chilarity. When you take the same piece of paper and try to roll it in varying unique angle then you get another chilarity. The paper therefore is a representation of how the latticed carbon atoms have been arranged to give the definite shape. The team of scientists who have made it possible to produce nanotube of much more predictable diameter was lead by Professor Chung Zwo.
Professor Chung Zwo who is a leading and proficient researcher at Viterbi Engineering School and Ming Zheng of Standards and Technology located in Maryland spearheaded the research. On the team there was also Jia Liu, Chuan Wang, and Bilu Liu to mention but a few who contributed immensely to the project. They successfully invented a system that produces nanotube of a much more predictable chilarity as well as diameter. This has been a dream of many scientist who have worked tirelessly to get this solution, which has now come to pass.
Understanding carbon nanotubes properties and other details
To get an in-depth understanding of carbon nanotubes , it is essential to understand how its grown. Carbon nanotubes are grown using a method of vapor Chemical deposition (VCD). A chemical gas is usually passed into a closed chamber that contains metal catalysts, that is nanoparticles that finally nanotubes grow. These nanoparticles are what essentially determine the diameter of nanotubes. The overriding problem has always been getting chilarity-oriented nanotubes with certain specifics. However, the recent Professor Zheng and team innovation has successfully been able to get to the bottom of the matter.
What Professor Zheng and his team managed to do is to perfect the separation process, picking and using only those only the best based on chilarity. They plant carbon nonotubes directly leaving out the catalyst, hence while the carbon nanotubes are used as seeds. Afterwards, a CVD methodology is applied to increase the length of nanotubes . These particular nanotubes had the same properties and chilarity as the seeds. This in scientific terms is known as nanotube cloning. The next challenge is to research and look at the finer details of the process of growth of nanotubes in the designated system. This will ensure that the process is improved.
Although this might take more work and research, it is a necessary step for the production of commercial quantities. It will ensure chilarity based nanotubes are produced on a large scale. This will also lead to production of better quality nanotubes to be used on electronic devices and applications. This scientific research is definitely going to change the game in the industry. Electronic companies are going to be forced to choose between silicon and nanotubes. The research by Professor Zheng has already been patented, and it is most likely to have a tremendous effect on the next generation of electronic devices.
