Due to their intuitiveness, flexibility, and relative numerical efficiency, the macroscopic
Maxwell–Bloch (MB) equations are a widely used semiclassical and semi …

The assumptions of conventional effective-mass theory, especially the one of continuity of
the envelope function at an abrupt interface, are reviewed critically so that the need for a …

With the rapid development of technologies for the fabrication of, as well as applications of
low-dimensional structures, the demands on characterization techniques increase. Spatial …

Progress in nanoscience is becoming increasingly dependent on simulation and modelling.
This is due to a combination of three factors: the reduced size of nano-objects, the …

A method for calculating the electronic states and optical properties of multidimensional
semiconductor quantum structures is described. The method is applicable to …

Spontaneous ordering of III-V alloys is known to cause a band-gap reduction‖ Δ E g‖ and
a splitting Δ E 12 of the valence-band maximum. Strain also leads to a valence-band …

The k⋅ p method has become the “standard model” for describing the electronic structure of
nanometer-size quantum dots. In this paper we perform parallel k⋅ p (6× 6 and 8× 8) and …

We have studied the nonlinear elasticity effects in zinc-blende and wurtzite crystallographic
phases of III-N compounds. Particularly, we have determined the pressure dependences of …

We calculate the rate of nonradiative Auger recombination in negatively charged CdSe
nanocrystals (NCs). The rate is nonmonotonic, strongly oscillating with NC size, and …

We apply photoluminescence, photoluminescence excitation, and time-resolved optical
spectroscopy for studying a set of In x Ga 1− x N/G a N periodic structures, which were …
