Quantam Dots:
A quantam dots are nanoparticle which possess change in the properties if an electron is removed or added. It is composed semiconductor material like CdS, ZnSe, InP etc. Its reduced size generate an electronic excitation to high energy, concentrating oscillator strength within few transition which gives unique quantam confined electronic and photonic properties. Quantam Dots shows strong resistance to chemical degradation, photo bleaching, photo stability and high quantam yields. In biochemistry, quantam dots are called redox group. In nanotechnology, it is known as quantam bits.

    LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor., which emits light when activated. When a fitting voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semi-conductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern. Appearing as practical electronic components in 1962, [9] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.…

    The representative SEM image of the G100-1000 nanopowders is given in Figure 3. The micrograph of the sample shows the agglomerated nanopowders with spherical morphology are relatively uniform and have average diameters of ~100 nm. The deviation in estimated sizes by SEM and XRD is due to the fact that XRD refers to single crystalline size while SEM refers to polycrystals.…

    Excition

    • 3 Pages

    An exciton is a bound state of an electron and a hole in an insulator (or semiconductor), or in other words, a Coulomb correlated electron/hole pair. It is an elementary excitation of a solid. A vivid picture of exciton formation is as follows: a photon enters a semiconductor, exciting an electron from the valence band into the conduction band. The missing electron in the valence band leaves a hole behind, of opposite electric charge, to which it is attracted by the Coulomb force. The exciton results from the binding of the electron with its hole; as a result, the exciton has slightly less energy than the unbound electron and hole. The wavefunction of the bound state is hydrogenic (an "exotic atom" state akin to that of a hydrogen atom). However, the binding energy is much smaller and the size much bigger than a hydrogen atom because of the effects of screening and the effective mass of the constituents in the material. Excitons can be treated in two limiting cases, which depend on the properties of the material in question. In semiconductors, the dielectric constant is generally large, and as a result, screening tends to reduce the Coulomb interaction between electrons and holes. The result is a Mott-Wannier exciton, which has a radius much larger than the lattice spacing. As a result, the effect of the lattice potential can be incorporated into the effective masses of the electron and hole, and because of the lower masses and the screened Coulomb interaction, the binding energy is usually much less than a hydrogen atom, typically on the order of 0.1 eV. This type of exciton was named for Sir Nevill Francis Mott and Gregory Wannier. In insulators, excitons tend to be much smaller, of the same order as the unit cell, so the electron and hole sit on the same site. This is a Frenkel exciton, named after J. Frenkel. The probability of the electron falling into (annihilating with) the hole is…

    A single-electron transistor consists of a small conducting island connected to the source and drain leads by tunnel junctions and connected to one or more gates. The nanometre scale conductive island is embedded in an insulating material. Gate signals are capacitive coupled to the island. Two gate signals can be applied to the island out of which one is optional. Here, only one electron can tunnel from source to drain. The processes that take place in this island (nano structure) are coulomb blockade phenomenon and single electron tunnelling.…
