Quantum coherent contributions in biological electron transfer
Many biological electron transfer (ET) reactions are mediated by metal centres in proteins. NADH:ubiquinone oxidoreductase (complex I) contains an intramolecular chain of seven iron-sulphur (FeS) clusters [1], one of the longest chains of metal centres in biology and a test case for physical models of intramolecular ET. In biology, intramolecular ET is commonly described as a diffusive hopping ...
متن کاملVibronic couplings and coherent electron transfer in bridged systems.
A computational strategy to analyze the dynamics of coherent electron transfer processes in bridged systems, involving three or more electronic states, is presented. The approach is based on partitioning of the Hilbert space of the time independent basis functions in subspaces of increasing dimensionality, which allows us to easily check the convergence of the time dependent wave function. Vibr...
متن کاملCoherent particle transfer in an on-demand single-electron source.
Electron transfer from a localized state in a quantum dot into a ballistic conductor generally results in particle-hole excitations. We study this effect, considering a resonance level with time-dependent energy coupled to particle states in the Fermi sea. We find that, as the resonance level is driven through the Fermi-level, particle-hole excitations can be suppressed for certain driving prot...
متن کاملElectron Transfer in Dye-Sensitized Nanocrystalline TiO2 Solar Cell
The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...
متن کاملVibrational control of electron-transfer reactions: a feasibility study for the fast coherent transfer regime.
Molecular vibrations and electron-vibrational interactions are central to the control of biomolecular electron and energy-transfer rates. The vibrational control of molecular electron-transfer reactions by infrared pulses may enable the precise probing of electronic-vibrational interactions and of their roles in determining electron-transfer mechanisms. This type of electron-transfer rate contr...
