High frequency limit of spectroscopy
Vladimir U. Nazarov, Roi Baer
We consider an arbitrary quantum mechanical system, initially in its ground-state, exposed to a time-dependent electromagnetic pulse with a carrier frequency and a slowly var…
Spontaneous charge carrier localization in extended one-dimensional systems
Vojtěch Vlček, Helen R. Eisenberg, Gerd Steinle-Neumann +3
Charge carrier localization in extended atomic systems has been described previously as being driven by disorder, point defects or distortions of the ionic lattice. Here we show fo…
Breaking the theoretical scaling limit for predicting quasi-particle energies: The stochastic GW approach
Daniel Neuhauser, Yi Gao, Christopher Arntsen +3
We develop a formalism to calculate the quasi-particle energy within the GW many-body perturbation correction to the density functional theory (DFT). The occupied and virtual orbit…
Biexciton generation rates in CdSe nanorods are length independent
Roi Baer, Eran Rabani
We study how shape affects multiexciton generation (MEG) rates in a semiconducting nanocrystal by considering CdSe nanorods with varying diameters and aspect ratios. The calculatio…
Theory of multiexciton generation in semiconductor nanocrystals
Eran Rabani, Roi Baer
We develop a generalized framework based on a Green's function formalism to calculate the efficiency of multiexciton gen-eration in nanocrystal quantum dots. The direct/indirect ab…
Can impact excitation explain efficient carrier multiplication in carbon nanotube photodiodes?
Roi Baer, Eran Rabani
We address recent experiments (Science 325, 1367 (2009)) reporting on highly efficient multiplication of electron-hole pairs in carbon nanotube photodiodes at photon energies near…
