Those semiconductors with a large exciton Bohr radius will exhibit significant size effects for nanoparticles below this value. For example, lead sulfide, PbS has a exciton Bohr radius of 18 nm which means nanoparticles below this size should exhibit significant quantum effects. In the case of ...
Intensifying the confinement or magnetic field and reducing the dot-size yields a blue-shift in the absorption peaks. However, the size effects are seen to be predominant in this role. The magnetic field tends to maximise the localisation of the particle, but leaves the peak position of the ...
). The driving forces for the photoinduced electron transfer and in-cage thermal charge recombination for irreversible donors were estimated according to the oxidation peak potentials because standard redox potentials were not available in these cases....
Corrections to the optical properties of cermets. I. Quantum size effectsFT-IRkanemiteRamanvibrational spectroscopyThe dielectric constant of metallic grains in real cermets is obtained using the formalism developed by Wood and Ashcroft, and the resonance structure derived from this formalism is ...
Nano-size effects on the dielectric and soft mode behaviors in the quantum paraelectric SrTiO3 were studied. Nanocrystalline SrTiO3 particles were prepared by the sol-gel method, and the particle sizes were controlled by treating temperatures. The sizes were determined to be from 12 to 44 nm ...

The effective potential provides a set back of the charge from the interface, and a quantization energy within the channel. Both of these effects lead to an increase in the threshold voltage. We find a threshold voltage shift of about 300mV when the effective potential is included in the ...
