•But it will come true with evolution of diamond or carbon chip.

•Now a days we are using silicon for manufacturing of electronic chips.

•It has many disadvantages when it is used in power electronics applications– Bulky sixe

– Slow operating speed

•By using carbon as manufacturing material, we can achieve smaller, faster and stronger chips.

Electronics without Silicon is unbelievable.

Silicon chips have reached the limit of their capacity to act as a semi-conductor ofelectricity. "Silicon Chips" according to MIT Professor of material science, Dr. Wuenschstates" Will melt into a puddle" at this rate and diamond is the solution to that problem. Amodern computer system in the office will generate heat at [100] degrees Celsius, enoughto heat a small office on a cold day.

This has prompted scientist to discover a replacement material that can handle moreelectricity with greater conductivity without over heating. This quest set off a world-widerace to take control of the computer and synthetic diamond industry.

In a single definition, Diamond Chip or Carbon Chip is an Electronic Chip manufactured on a diamond structure Carbon wafer

What is diamond chip?

Apollo is owned by a first rate scientist whose dream was to create a better computerpower chip..He knew that the ultimate conductor is the diamond itself. Diamond canconduct more electricity without over heating than any material on earth.. He also knewthat even the world's best De Beer mine diamonds do not have consistent properties thatyou can depend on to make computer chips.

How is it possible ?Diamond structural carbon is non conducting in nature. To make it conducting, doping process is performed.

Boron-- as the p-type. Nitrogen--as the n-type.

What is carbon

nano tube?oJust fold the graphene sheet into a tube like structureoIt is a nano size cylinder of carbon atoms.oIt has less than one nanometer diameter. Fig: Carbon nanotubes

made step by step.

o Move charge around much faster before thing stop workingo Diamond transistors can operate at much higher temperature o Larger(wider) band gapo Thermal conductivity

Diamond excels in its electronic properties

In the addressable field emitter array concept, electron beams from amorphous diamond cathodes "write" circuit patterns onto a computer chip wafer. The technology could help chip makers attain the degrees of chip density that designers are approaching.

New computer chip technologycould fill production gap

Why the name DIAMOND CHIP?

Lonsdaleite is an sp3 bondage allotropicform of carbon i.e. 3-dimentional CNT.

Crystal structure of Lonsdaleite looks exactly like diamond.

Thus diamond chip replaces the need of silicon in every aspect in future generations. The chips would be most useful in devices located near hot-burning engines, such as those used in automobiles or airplanes.
