STUDY OF QUANTUM DOT CHARACTERISTICS AND APPLICATIONS WITH SEMICONDUCTING CARBON NANOTUBE

The low dimensional materials exhibit unique chemical and physical characteristics that are not present in their bulk counter parts. The confinement of electrons and holes to low dimension structures results in structural modifications of quantum-size effects. The “quantum confinement effect” enables semiconductors to have atom-like structures. It can be explained by a particle in a quantum box. Quantum dots are tunable artificial atoms that provide an ideal laboratory for exploring the physics of atoms and molecules and have many potential applications. Quantum Dots are most commonly assembled from semiconductor materials. They can display fluorescence in the visible range of light when excited with UV. A specific wavelength can be generated by each class of nano size materials. This makes it possible to tune the emission by altering the quantum dot size toward a particular wavelength. In this efforts characterization of quantum dots from semi conduction materials and some of their applications have been studied.
