Influence of quantum confinement on the carrier contribution to the elastic constants in quantum confined heavily doped non-linear optical and optoelectronic materials: simplified theory and the suggestion for experimental determination

Nanophotonics for 21st Century

“…It has been found, taking different heavily doped quantum confined materials that, the carrier contribution to the elastic constants increases with increase in electron statistics and decrease in film thickness in ladder like manners for all types of quantum confinements with different numerical values, which are entirely dependent on the energy band constants. This contribution is greatest in quantum dots and least in quantum wells together with the fact the heavy doping enhances the said contributions for all types of quantum-confined materials (Baruah et al, 2007). To understand the size quantization on the luminescence (see figure 24) from the metal nanoparticles a simplified model for the band structure is developed.…”

“…Fundamental research on nanophotonics leads to applications in communications technology, lasers, solid-state lighting, data storage, lithography, biosensors, optical computers, imaging, solar cells, lightactivated medical therapies, displays, and smart materials to cite a few (Empedocles et al, 1997;Baruah et al, 2007;Rahmani et al, 1997;Nezhad et al, 2007;Shen et al, 2000;Levy et al, 2004). Some of the important areas that will find large market in next ten to fifteen years from now are identified and represented in figure 25.…”
