An electron wave packet formed in a semiconductor heterostructure containing a quantum well covered by a metal surface is considered. It is demonstrated that the potential of the charge induced by the electron wave packet on the conducting surface possesses a component of lateral confinement stabilizing its shape. The existence of electron solitons, i.e., running electron wave packets propagati...

We present numerical simulations of charge transport through semiconductor nanostructures performed within the Green’s function formalism. The commonly used algorithm to compute the conductance of nanostructures in this formalism has been adapted for parallel execution on both multicore computers and general-purpose graphics processing units (GPU). Additionally, memory utilization has been opti...

95 The outstanding light-trapping and electromagnetic-fieldconcentrating properties of surface plasmons open up a wide range of applications in the field of plasmonics1. Localized surface plasmon resonance (LSPR) can occur in properly designed nanostructures in which confined free electrons oscillate with the same frequency as the incident radiation and eventually enter resonance, giving rise t...

The formation of Ge self-organized quantum dots (huts) on the Si(001)-2x1 surface has attracted much attention due to its status as the premier model system for investigating straininduced semiconductor nanostructure growth. Our findings on this strained surface structure imply that both the structure and the strain of semiconductor nanostructures may be controlled through the understanding of ...

In this study, our recent research activities on nanophotonic devices with semiconductor quantum nanostructures are reviewed. We have developed a technique for nanofabricating of high-quality and high-density semiconductor quantum dots (QDs). On the basis of this core technology, we have studied next-generation nanophotonic devices fabricated using high-quality QDs, including (1) a high-perform...

Multidimensional Coherent optical Spectroscopy (MDCS) is an elegant and versatile tool to measure the ultrafast nonlinear optical response of materials. Of particular interest for semiconductor nanostructures, MDCS enables the separation of homogeneous and inhomogeneous linewidths, reveals the nature of coupling between resonances, and is able to identify the signatures of many-body interaction...
