Charge and spin control of ultrafast electron and hole dynamics in single CdSe/ZnSe quantum dots
Christopher Hinz,P. Gumbsheimer,C. Traum,M. Holtkemper,B. Bauer,Johannes Haase,Suddhasatta Mahapatra,Alexander Frey,Karl Brunner,Doris E. Reiter,Tilmann Kuhn,Denis V. Seletskiy,Alfred Leitenstorfer +12 more
TL;DR: In this paper, the authors present an analysis of the relationship between the number of atoms and the amount of light in a photon and the distance from the photon to the photon in order to determine the probability of a photon being a photon.
Band offsets and band bending at heterovalent semiconductor interfaces
TL;DR: In this paper, a comprehensive study of band offsets and band bending at heterovalent semiconductor heterointerfaces is presented, which is based on a band bending model accounting for variable band offsets, interface state density and atomic interdiffusion profiles depending on growth start.

TL;DR: Semiconductor quantum dots are promising systems for robust and scalable quantum information processing as discussed by the authors, which can be envisioned with femtosecond light pulses, if the involved quantum states are separated by at least tens of meV.
