Tight-binding modeling of charge migration in DNA devices
G. Cuniberti, E. Macia, A. Rodriguez +1
Long range charge transfer experiments in DNA oligomers and the subsequently measured -- and very diverse -- transport response of DNA wires in solid state experiments exemplifies…
Long range correlations in DNA : scaling properties and charge transfer efficiency
Stephan Roche, Dominique Bicout, Enrique Macia +1
We address the relation between long range correlations and charge transfer efficiency in aperiodic artificial or genomic DNA sequences. Coherent charge transfer through the HOMO s…
Dynamical phenomena in Fibonacci Semiconductor Superlattices
Enrique Diez, Francisco Dominguez-Adame, Enrique Macia +1
We present a detailed study of the dynamics of electronic wavepackets in Fibonacci semiconductor superlattices, both in flat band conditions and subject to homogeneous electric fie…
Can fractal-like spectra be experimentally observed in aperiodic superlattices?
Enrique Macia, Francisco Dominguez-Adame
We numerically investigate the effects of inhomogeneities in the energy spectrum of aperiodic semiconductor superlattices, focusing our attention on Thue-Morse and Fibonacci sequen…
Fluorescence decay in aperiodic Frenkel lattices
Francisco Dominguez-Adame, Enrique Macia
We study motion and capture of excitons in self-similar linear systems in which interstitial traps are arranged according to an aperiodic sequence, focusing our attention on Fibona…
Physical nature of critical wave functions in Fibonacci systems
Enrique Macia, Francisco Dominguez-Adame
We report on a new class of critical states in the energy spectrum of general Fibonacci systems. By introducing a transfer matrix renormalization technique, we prove that the charg…
Three-Dimensional Effects on the Electronic Structure of Quasiperiodic Systems
