The document discusses a colloquium presentation on diamond chips. Diamond chips are manufactured from diamond structured carbon wafers and use carbon nanotubes as their major component. To make diamond conductive for electronics applications, it must be doped with elements like boron or nitrogen. Carbon nanotubes have excellent electrical and thermal properties and high strength. They allow for smaller, faster components that can operate at high temperatures. While diamond chips provide advantages over silicon, their production is more expensive and doping is more difficult due to diamond's structure. Overall, the presentation suggests that carbon chips may replace silicon in electronics in the future.

COLLOQUIUM PRESENTATION ON DIAMOND CHIP RAJKIYA ENGINEERING COLLEGE AMBEDKARNAGAR DEPARTMENT OF INFORMATION TECHNOLOGY UNDER THE SUPERVISION OF MISS RITU VERMA Submitted to Presented by Miss Anamika Srivastava Arnav singh
INTRODUCTION What is Diamond chip? How is it possible?  CNT Properties of CNT Application of CNT ADVANTAGES LIMITATIONS CONCLUSION
•Electronics without silicon is unbelievable. •Disadvantages when used in power electronics application. Bulk in size Slow 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 –type Nitrogen as n-type
• 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 .
PROPERTIES STRENGTH HARDNESS ELECTRICAL THERMAL ONE DIMENSIONAL TRANSPORT
PROPERTIES 1. STRENGTH Carbon nanotube are strongest and stiffest materials discovered in term of tensile strength strength and elastic modulas 2. HARDNESS It can withstand a pressure up To 24 Gpa a without diformation
ELECTRICAL  IT HAS HIGH ELECTRICAL CONDUCTIVITY  VERY LESS RESISTANCE  THERE IS NO ANY ELECTRO MIGRATION  IT CAN CARRY HIGH CURRENT DENSITIES WHICH IS 1000 TIMES THAT OF COPPER  BOTH METAL AND SEMICONDUCTOR CAN BE FORMED
THERMAL  ITS 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 CNT  INFORMATION AND COMMUNICATION  MATERIALS AND MANUFACTURING  BIOMEDICAL  TO MAKE SENSORS  TO MAKE TRANSISTORS  CAPACITORS
ADVANTAGES SMALLER COMPONENTS ARE POSSIBLE ITS WORK AT HIGH TEMPRATURE FASTER THAN SILICON CHIP LARGER POWER HANDLING CAPACITY
LIMITATIONS  MUCH MORE EXPENSIVE THAN SILICON  DOPING PROCESS IS VERY HARD TO PERFORM DUE TO THE DIAMOND STRUCTUREM, THAN IN SILICON
CONCLUSION CARBON CHIP WILL REPLACE NEED OF SILICON IN EVERY ASPECT IN COMING YEAR
