Efficiency of the coherent biexciton admixture mechanism for multiple exciton generation in InAs nanocrystals
P. Kowalski, P. Machnikowski
We study the coherent mixing between two-particle (single exciton) and four-particle (biexciton) states of a semiconductor nanocrystal resulting from the coulomb coupling between s…

Coulomb matrix elements for the impact ionization process in nanocrystals: the envelope function approach
Piotr Kowalski, Łukasz Marcinowski, Paweł Machnikowski
We propose a method for calculating Coulomb matrix elements between exciton and biexciton states in semiconductor nanocrystals based on the envelope function formalism. We show tha…
