About the Course :
- Today Nanotechnology has not only assumed
strategic importance in the technical
world, it is also being effectively used
in almost every field of human endeavor,
ranging from space exploration to robotics
and weapon manufacturing to communication
etc.
- Nanotechnology - the science of the
miniature, and the technology of the future
- is one of the most exciting and wide
area of research which may lead to the
greatest technological advances of the
21st century. It is a global phenomenon
and an emerging field, that finds its
way into a myriad of industrial applications
spanning across all areas of science and
technology. A form of molecular engineering,
it is the technology associated with the
creation and scrutiny of minute objects,
measuring between 1 to 100 nanometers. Nanotechnology
can be defined as the application of science,
engineering and technology to develop
novel materials and devices in different
fields in the nano-range.
- With the international market for nanotech
products and applications projected to
grow in the next decade to over $600 billion
annually, India is poised for a bright
future in nanotechnology.
- The main sectors in this field are:-
- Nano-Electronics: Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. Nano-electronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanics properties need to be studied extensively.
- Nano-Photonics - Nanophotonics or Nano-optics is the study of the behavior of light on the nanometre scale. It is considered as a branch of optical engineering which deals with optics, or the interaction of light with particles or substances, at deeply subwavelength length scales. Technologies in the realm of nano-optics include near-field scanning optical microscopy (NSOM), photoassisted scanning tunnelling microscopy, and surface plasmon optics.
- Nano-Lithography : Nanolithography refers to the fabrication of nanometer-scale structures, meaning patterns with at least one lateral dimension between the size of an individual atom and approximately 100 nm. Nanolithography is used during the fabrication of leading-edge semiconductor integrated circuits or nanoelectromechanical
