Incomplete electronic relaxation and population upconversion in quantum dots
K. Kral, Z. Khas, P. Zdenek
We calculate the electronic relaxation of a single electron in a quantum dot with two electronic orbital states, and with the electronic coupling to the longitudinal optical modes…

Sub-wetting layer continuum states in quantum dot samples
K. Kral, P. Zdenek
In the polar semiconductor samples of the self-organized quantum dots, grown by the Stranski-Krastanow growth method, the lowest energy extended states of the electronic excitation…

Femtosecond to picosecond electron-energy relaxation and Froehlich coupling in quantum dots
K. Kral, Z. Khas
Electron relaxation in quantum dots is studied theoretically in polar semiconductor materials, with an emphasis put on the phonon-bottleneck problem and electron-LO-phonon coupling…
