DIAMOND CHIP
[attachment=66731]
INTRODUCTION
Electronics without silicon is unbelievable, but it will come true with evolution of diamond or carbon chip.
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 A CARBON NANOTUBE?
Carbon nano-tubes 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 nano tube.
Carbon nano tube properties depend on how you roll the sheet.
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.
FASTER THAN SILICON CHIP
Mobility of the electrons inside the doped diamond structural carbon is higher than that of in the silicon structure. As the size of the silicon is higher than that of carbon, the chance of collision of electrons with larger silicon atoms increases. But the carbon atom size is small, so the chance of collision decreases.
LARGER POWER HANDLING CAPACITY
For power electronics application silicon is used, but it has many disadvantages such as bulk in size, slow operating speed, less efficiency, lower band gap etc at very high voltages silicon structure will collapse. Diamond has a strongly bonded crystal structure. So carbon chip can work under high power environment. We can connect high power circuit direct to the diamond chip.
Conclusion
Thus diamond chip replaces the need of silicon in every
aspects in future generation.
