This is a very general question Suganthi. In a nutshell Nanotechnology is working with materials at a 10-9 m scale. It is literally building the component atom by atom. It is so revolutionary because the properties of the bulk elements change at such a small level. Most current research in nanotechnology is focused on manufacturing single walled and multi walled carbon nanotubes. When regular materials are "doped" with these carbon nanotubes, the scientists have the ability to changes the fundamental properties of that material (e.g. Increased conductivity, lower MP and so on). Semiconductors have been silicon based till now. With nanotechnology, there is a potential for carbon based semiconductors with maybe advanced properties than silicon. For more info Google the phrase and I am sure it will link you to umpteen websites that explain carbon nanotubes (CNTs) and related researches.
Specifically, India is a country (amongst others)  that has shown great interest in Nanotechnology of late. IIT Mumbai is setting up a nanotechnology research centre in Powaii. So you can probably contact them if you need more info too.

Hope this helps,

Dear All,

Pls explain me about nanotechnology ?  How does it effect the
semiconductor field ?

Thanks and Regards
Suganthi,CID
