The silicon transistors in your computer may be replaced by transistors based on carbon nanotubes.A carbon nanotube is a molecule in form

of a hollow cylinder with a diameter of around a nanometer which consist of pure carbon.

Nanorods is a upcoming technology in the displays techniques due to less consumption of electrically and less heat emission.

Size of the microprocessors are reduced to greater extend.Researchers at North Carolina State University says that growing arrays of magnetic nanoparticles, called nanodots.

Nanotechnology in Electronics

Electrodes made from nanowires enables flat panel displays to be flexible as well as thinner than current flat panel displays.

Nanolithography is used for fabrication of chips.

The transistors are made of nanowires, that are assembled on glass or thin films of flexible plastics.

E- paper, displays on sunglasses and map on car windshields.
