Charge-transfer polarons and excitons
Physical Review B, 1991We show that polarons and excitons of charge-transfer origin arise quite naturally in the {ital p}-{ital d} model of high-temperature superconductors. We consider the limit in which on-site Coulomb repulsion on both Cu and O is taken to be infinite and treat the Cu-O repulsion {ital U}{sub {ital p}{ital d}} in the Hartree-Fock approximation.

Charge Transfer Vibronic Excitons: Charge-Transfer Lattice-Instability Effects
Physics of the Solid State, 2005Two aspects for investigating bipolaronic excitons [charge transfer vibronic exciton (CTVE)] in ionic-covalent solids are considered. These aspects are predictions of the charge-transfer lattice instability corresponding to charge transfer and lattice anharmonicity, as well as to repulsion between different types of CTVEs in the order parameter field ...

Lack of Charge Transfer in Aromatic Charge—Transfer Complexes
The Journal of Chemical Physics, 1964Halogen pure electrical quadrupole resonance frequencies have been measured in the three 1:1 complexes, CBr4·p-xylene, CCl4·p-xylene, and Br2·benzene. From an examination of the measured frequencies of the complexes and the halogen-containing compounds (CBr, CCl4, and Br2) together with information from the x-ray structure determinations for two of the

Proceedings of the IEEE, 1979
Linear discrete-time (sampled-data) filters can be implemented in monolithic form on an MOS chip using a variety of recently developed and newly emerging techniques without requiring analog-to-digital conversion. An analog signal sample can be represented by an isolated quantity of charge and such packets of charge can be stored, transferred, and ...

In contrast to lithium-ion batteries where lithium ions carry the charge, a proton battery, making use of a hydrated Prussian blue analogue electrode, is shown to be able to transmit charges in the fashion of the Grotthuss mechanism, displaying ultrafast-rate and ultralong-life properties.

This chapter reviews the developments that have enabled the employment of many-body, reactive variable charge potentials in atomic-scale simulations. In particular, the formalisms for the charge optimized many-body, or COMB, potentials are presented and their application to chemistry in classical molecular dynamics reactions is reported.

Sensor Review, 1999
While the transference of charge is an essential aspect of every capacitance sensor, a relatively new form of sensor makes overt use of the principle of charge conservation first deduced by Watson in the 1740s. Updated to use a microcontroller, mosfet switches, fet‐input opamps and band gap references, the principle of charge transference can be used ...

Charge transfer spectra in highly ionic crystals correspond to electron transfer between neighboring atoms. They can be classified as donor or acceptor, depending upon whether the metal atom donates or accepts an electron. The essential differences between these two kinds of transitions are emphasized, and a simple criterion to establish which type is ...
