APPLICATION OF CARBON NANO TUBES IN FLEXIBLE ELECTRONICS
[attachment=17378]
INTRODUCTION
A new generation of computers and smartphones could run much faster if they were made from the world's thinnest substance, scientists have claimed.
The researchers found that electrons travel a lot more quickly in grapheme than they do in silicon; the substance current computer chips are made out of.
And given the material's flexible properties, the commercial benefits would be truly groundbreaking - leading to phones and computers that could be rolled up like a pencil. Here in this seminar we discuss about the current
SELECTION OF THE TOPIC
Electronics is not a field to be simply experimented and stydied. But the facts that we study and invent should reach the society with ease. Then only we can tell that electronics is a success. The most important thing to be done is to help the technology reach the common. For the common man to have access to these technologies we, the engineers should work on it and make electronics cheaper and useful. Nanotechnology actually makes systems smaller and thereby reduces cost on mass production. Carbon nano tubes along with flexible electronics make this a reality. The seminar gives some basic concepts of carbon nano tubes and some of its applications in flexible electronics.
CARBON NANO TUBES AND ITS STRUCTURE
It is an allotrope of carbon which is cylindrical in shape with length to diameter ratio 132000000:1.it finds numerous applications in the fields of nanotechnology, optics, electronics; material science etc.It is of great importance due to its thermal, electrical and mechanical properties.
A carbon nano tube a long, cylindrical, hollow tube with 1 atom thick wall of graphene sheet. Its rolled at specific discrete angles known as chiral.The properties of CNT is defined by its rolling angle and radius. The two types of CNTs are single walled and multi walled.
