Abstract:
With the advent of nanotechnology, many important fields have come up with the diverse
applications in various interdisciplinary areas and indeed it has been observed that ‘there’s plenty
of room at the bottom’ that was first quoted by the physicist Richard P. Feynmann. One of the
most important scientific areas that have developed recently is Nanomaterials which ultimately
lead to the emergence of nanotechnology. Nanomaterials show unique properties arising from
their nanoscale dimensions. These special properties of the nanomaterials can be exploited to
attain several useful applications. One such nanomaterial with huge potential are the Quantum
Dots. These are tiny particles of the semiconducting material which confines the motion of
conduction band electrons, valence band holes or excitons (bound pairs of conduction band
electrons and valence band holes) in all three spatial directions.
