Nanotechnology is a cross-section technology concerned with research and construction in tiny structures. A nanometer corresponds to a millionth of a millimeter. It is a discipline which offers more potential for innovative applications than any other as special physical laws apply on the nano-level. Manipulation of the nanostructure can alter the optical, electrical or chemical properties of established materials.
The ideas and concepts behind the nanoscience and nanotechnology started with a talk entitled "There's Plenty of Room at the Bottom" by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn't until 1981, with the development of the scanning tunneling microscope that could "see" individual atoms that modern nanotechnology began.
I study the fabrication of different nanostructures such as silicon and germanium nanowires, and application of light at the nanoscale by plasmonics nanostructures.
