INTRODUCTION
Electronics with out silicon is unbelievable, 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 electronic applications, such as bulk size, slow operating speeds, etc…
By using carbon as manufacturing material, we can achieve smaller, faster and stronger chips
What is Diamond chip?
Diamond chip is nothing but carbon chip.
Carbon chip is an electronic chip manufactured on a diamond structural carbon wafer.
The major component using carbon is (CNT) ”CARBON NANOTUBE”
WHAT IS A CARBON NANOTUBE…
Carbon nanotubes were discovered in 1991.
It is a nano - size cylinder of carbon atoms.
They are made of one or several concentric walls in which carbon atoms are arranged in hexagonal pattern, measuring several tens of microns in length and less than a few nanometres in diameter.
HOW NANOTECHNOLOGY WORKS…
Imagine a sheet of carbon atoms, which would look like a sheet of hexagons.
If you roll that sheet into a tube, you'd have a carbon nanotube.
Carbon nanotube properties depend on how you roll the shee
CARBON FEATURES…
Carbon will succeed silicon as the predominate semiconducting material for the integrated circuits of the future.
Carbon--which sits just above silicon on the periodic table can surpass silicon’s abilities in thermal performance, frequency range and perhaps even superconductivity.
One-dimensional carbon
1nm-diameter nanotubes-Nanotubes will appear first as printable "inks" that are 10 times faster than competing organic transistors.
zero-dimensional carbon:
60-atom, hollow spheres of carbon called fullerenes--could answer silicon's inability to attain high-temperature superconductivity.
CARBON TRANSISTORS
Transistors less than one-quarter the size of the tiniest silicon ones - and potentially more efficient - can be made using sheets of carbon just one-tenth of a nanometer thick, research shows.
The transistors are made of graphene, a sheet of carbon atoms in a flat honeycomb arrangement.
When placed a piece of graphene on top of silicon and positioned this over a metallic gate.
Acid was used to dissolve the silicon, leaving graphene suspended across 500 nm gaps.
CONCLUSION :
Thus diamond chip replaces the need of silicon in every aspect in future generations…..
