INTRODUCTION•Electronics without silicon is unbelievable.•Disadvantages when used in power electronics application.Bulk in sizeSlow operating speed etc.

What is Diamond chip?Diamond Chips are

manufactured Diamond structural Carbon wafer.

Diamond chip are also called carbon chip. Major component in these Diamond Chip are carbon nanotube.

Although structure of carbon is non-conducting in nature. So we have to perform the doping method to fulfill our requirement.

How is it possible?Diamond structural carbon is non conducting in nature

To make it conducting , doping process performed

Boron as p –typeNitrogen as n-type

CNT(CARBON NANO TUBE)

• Carbon nanotube were discovered in 1991• A carbon nanotube is a tube-shaped material, made of carbon, having a diameter measuring on the nanometer scale.• The characteristics of nanotubes can be different depending on how the graphene sheet has rolled up to form the tube causing it to act either metallic or as a semiconductor .

PROPERTIES1. STRENGTHCarbon nanotube are strongest and stiffest

materialsdiscovered in term of tensile strength strength and elastic modulas2. HARDNESSIt can withstand a pressure upTo 24 Gpa a withoutdiformation

ELECTRICALIT HAS HIGH ELECTRICAL

CONDUCTIVITYVERY LESS RESISTANCETHERE IS NO ANY ELECTRO MIGRATIONIT CAN CARRY HIGH CURRENT

DENSITIES WHICH IS 1000 TIMES THAT OF COPPER

BOTH METAL AND SEMICONDUCTOR CAN BE FORMED

THERMALITS WORK ON VERY HIGH AND LOW

TEMPRATURE

ONE DIMENSIONAL TRANSPORT

BECAUSE OF THE NANOSCALE DIMENSIONS ELECTRONS PROPAGATE ONLY ALONG THE TUBE’S AXIX

CARBON NANOTUBE ARE FREQUENTLY REFERRED TO AS ONE DIMENSIONAL

APPLICATION OF CNTINFORMATION AND COMMUNICATIONMATERIALS AND MANUFACTURINGBIOMEDICALTO MAKE SENSORSTO MAKE TRANSISTORSCAPACITORS

ADVANTAGESSMALLER COMPONENTS ARE POSSIBLE

ITS WORK AT HIGH TEMPRATURE

FASTER THAN SILICON CHIPLARGER POWER HANDLING CAPACITY

LIMITATIONSMUCH MORE EXPENSIVE THAN

SILICON

DOPING PROCESS IS VERY HARD TO PERFORM DUE TO THE DIAMOND STRUCTUREM, THAN IN SILICON

CONCLUSIONCARBON CHIP WILL REPLACE NEED OF SILICON IN EVERY ASPECT IN COMING YEAR
