Introduction to

Nanotechnology


Origin of Nanotechnology “The birth of nanotechnology is popularly taken to

be 1989, when IBM Fellow Don Eigler used a scanning tunneling microscope to create the company’s logo out of xenon atoms.”

By working with xenon and nickel at very low temperatures, an IBM scientist was the first to use a tiny needle to position individual atomson a surface.


Nanotechnology will be an integral part of next-generation technology .

It deals with fabrication, study and tailoring the device dimensions at atomic and molecular level.

Nano a Greek word that means Dwarf.A nanometer is one billionth of a meter i.e . 1nm = 10 -9 mGenerally the device dimensions are shrinked down

to 100 nanometers or even lesser.Richard Feynman Quoted “There’s a plenty of

room at the bottom”.RTSAM 27-28 Jan, 2010 Malegaon
