WHAT IS NANOTECHNOLOGY?WHAT IS NANOTECHNOLOGY?

Nanotechnology deals with the study ofNanotechnology deals with the study of

Materials of size Materials of size 1010-9 m.-9 m.

The materials in nanometer scale posses novel The materials in nanometer scale posses novel properties such as high efficiency &properties such as high efficiency &

capacity than the normal materials.capacity than the normal materials.

WHAT IS NANO CIRCUTRY?WHAT IS NANO CIRCUTRY?

Nanocircuitry deals with minimization of circuit Nanocircuitry deals with minimization of circuit size to nano scale.size to nano scale.

It helps the scientists & engineers in reduction It helps the scientists & engineers in reduction of the size of computers & other electronic of the size of computers & other electronic devices.devices.

The age of nanocircuitary begins with the The age of nanocircuitary begins with the invention of nanotransistors & ultra capacitors.invention of nanotransistors & ultra capacitors.

MOORE’S LAW:MOORE’S LAW:moore’s law states that,”the moore’s law states that,”the

speed of the computer will be speed of the computer will be doubled in every 18 to 24 doubled in every 18 to 24

months.months.This is made possible by This is made possible by increasing the number of increasing the number of

transistors fitted into a circuittransistors fitted into a circuit..

CAPACITORS ARE ENERGY SAVING CAPACITORS ARE ENERGY SAVING DEVICES.DEVICES.

THEY CONSIST OF TWO TERMINALS THEY CONSIST OF TWO TERMINALS EACH STORE POSITIVE OR NEGATIVE EACH STORE POSITIVE OR NEGATIVE CHARGES.CHARGES.

THE ULTRA CAPACITORS ARE MADE THE ULTRA CAPACITORS ARE MADE FROM CARBON NANO TUBES.FROM CARBON NANO TUBES.

THEY HAVE HIGH THEY HAVE HIGH RELIABILITY,COMPACTNESS.RELIABILITY,COMPACTNESS.

TRANSISTORS:TRANSISTORS:

Transistors are the devices that forms the Transistors are the devices that forms the integral parts of the circuit.integral parts of the circuit.

Transistors converts the weak signals into Transistors converts the weak signals into stronger signals.stronger signals.

To convert the transistors to nano scale we To convert the transistors to nano scale we are in need of switch on to carbon base are in need of switch on to carbon base instead of silicon.instead of silicon.
