Linear and nonlinear optical properties of multilayered spherical quantum dots: Effects of geometrical size, hydrogenic impurity, hydrostatic pressure and temperature

Threshold pump intensity effect on the refractive index changes in InGaN SQD: Internal constitution and size effects

“…Therefore, one can affirm that in order to obtain a significant changes in RI, it should be used a large dot radius and higher excited pump intensity. This result is quite agreement with the finding data [20,22,23,[29][30][31][32][33][34][35].…”

Quadratic Electro-Optic Effect and Electro Absorption Process of Multi-layer Spherical Quantum Dot Enhanced by Metal Nanoparticle

“…Among the various types of QDs, multi-layer spherical quantum dot (MSQD) exhibits an interesting behavior, which one of the outstanding properties of MSQD is the changes in energy spectrum which occur when some kind of modification is applied to the system. These modifications can be done by changing the size or the geometry of the system and has been studied theoretically by many researchers [19][20][21][22].…”

The linear and nonlinear optical properties of an off-center hydrogenic donor impurity in nanowire superlattices: Comparison between arrays of spherical and cylindrical quantum dots

“…One of the main research topics in the area of optoelectronic deals with the intersubband optical transitions between the quantized energy levels [21]. Due to the generally larger values of transition dipole elements, in the case of intense optical intensities, nonlinear optical processes in the nanostructures are not negligible [22][23][24]. Meanwhile, the dependence of the optical transition energy on the confinement strength, shape and type of nanostructures make it possible to adjust the resonance conditions [25].…”
