Quantifying the impact of phonon scattering on electrical and thermal transport in quantum dots
B. Goldozian, G. Kiršanskas, F. A. Damtie +1
We report the inclusion of phonon scattering to our recently established numerical package QmeQ for transport in quantum dot systems. This enables straightforward calculations for…
Optimization Schemes for Efficient Multiple Exciton Generation and Extraction in Colloidal Quantum Dots
Fikeraddis A. Damtie, Khadga J. Karki, Tõnu Pullerits +1
Multiple exciton generation is a process in which more than one electron hole pair is generated per absorbed photon. It allows us to increase the efficiency of solar energy harvest…
Time Dependent Study of Multiple Exciton Generation in Nanocrystal Quantum Dots
Fikeraddis A. Damtie, Andreas Wacker
We study the exciton dynamics in an optically excited nanocrystal quantum dot. Multiple exciton formation is more efficient in nanocrystal quantum dots compared to bulk semiconduct…
Transport in serial spinful multiple-dot systems: The role of electron-electron interactions and coherences
Bahareh Goldozian, Fikeraddis A. Damtie, Gediminas Kiršanskas +1
Quantum dots are nanoscopic systems, where carriers are confined in all three spatial directions. Such nanoscopic systems are suitable for fundamental studies of quantum mechanics…
