Efficient Charge Separation in Multidimensional Nanohybrids
Nano Letters, 2011We report unidirectional charge transfer in multidimensional nanohybrids, consisting of a quantum dot, an electronically active molecular linker, and a carbon nanotube. After covalent attachment to the nanotube, only emission consistent with the negatively charged quantum dot exciton ion rather than the neutral exciton is observed, showing nearly ...

Primary charge separation in Photosystem II
Photosynthesis Research, 2000In this Minireview, we discuss a number of issues on the primary photosynthetic reactions of the green plant Photosystem II. We discuss the origin of the 683 and 679 nm absorption bands of the PS II RC complex and suggest that these forms may reflect the single-site spectrum with dominant contributions from the zero-phonon line and a pronounced ...

Stable photoinduced charge separation in heptacene
Chemical Communications, 2007Heptacene, generated in inert gas matrices by photobisdecarbonylation of a bridged alpha-diketone precursor, undergoes ionization into radical anion and radical cation upon UV irradiation.

Photoinduced Charge Separation in Molecular Silicon
Chemistry – A European Journal, 2016AbstractInterest in molecular silicon semiconductors arises from the properties shared with bulk silicon like earth abundance and the unique architectures accessible from a structure distinctly different than rigid π‐conjugated organic semiconductors.

Stick slip, charge separation and decay
pure and applied geophysics, 1986Measurements of charge separation in rock during stable and unstable deformation give unexpectedly large decay times of 50 sec. Time-domain induced polarization experiments on wet and dry rocks give similar decay times and suggest that the same decay mechanisms operate in the induced polarization response as in the relaxation of charge generated by ...

Nanorod Heterostructures Showing Photoinduced Charge Separation
Small, 2007AbstractSize‐ and shape‐dependent property modifications of semiconductor nanocrystals have been a subject of intense interest because of their potential for future engineering devices. The bandgap and related optical‐property tuning of these materials are mainly governed by the nature of their band edges.

INTERFACIAL CHARGE SEPARATION IN PHOTORECEPTOR MEMBRANES
Photochemistry and Photobiology, 1980Abstract— A rapid change in an interfacial electric potential of isolated bovine rod outer‐segment disc membranes occurs upon illumination. This potential change, which has been detected by the use of spin labelled hydrophobic ions, apparently occurs within a low dielectric boundary region of the membrane near the external (cytoplasmic) surface and is ...
