A Theoretical Investigation of Charge Transfer Dynamics from Sensitized Molecule D35CPDT Dye to SnO_2 and TiO_2 Semiconductor

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2022
In this research, the dynamics process of charge transfer from the sensitized  D35CPDT dye to tin(iv) oxide( ) or titanium dioxide (  ) semiconductors are carried out by using a quantum model for charge transfer.

Interfacial Charge-Transfer Transitions for Direct Charge-Separation Photovoltaics

Energies, 2020
Photoinduced charge separation (PCS) plays an essential role in various solar energy conversions such as photovoltaic conversion in solar cells. Usually, PCS in solar cells occurs stepwise via solar energy absorption by light absorbers (dyes, inorganic ...

Spin and charge ordering in self-doped Mott insulators [PDF]

, 1999
We have investigated possible spin and charge ordered states in 3d transition-metal oxides with small or negative charge-transfer energy, which can be regarded as self-doped Mott insulators, using Hartree-Fock calculations on d-p-type lattice models.

Functional Charge Transfer Plasmon Metadevices

Research, 2020
Reducing the capacitive opening between subwavelength metallic objects down to atomic scales or bridging the gap by a conductive path reveals new plasmonic spectral features, known as charge transfer plasmon (CTP).

Charge orders in organic charge-transfer salts

New Journal of Physics, 2017
Motivated by recent experimental suggestions of charge-order-driven ferroelectricity in organic charge-transfer salts, such as κ -(BEDT-TTF) _2 Cu[N(CN) _2 ]Cl, we investigate magnetic and charge-ordered phases that emerge in an extended two-orbital ...

Weak ferroelectric charge transfer in layer-asymmetric bilayers of 2D semiconductors

Scientific Reports, 2021
In bilayers of two-dimensional semiconductors with stacking arrangements which lack inversion symmetry charge transfer between the layers due to layer-asymmetric interband hybridisation can generate a potential difference between the layers.

Photoinduced charge transfer in two-photon absorption

Results in Optics, 2021
The visual method is used to theoretically discuss the influence of different external electric fields on the photo-induced charge transfer of the donor-bridge-acceptor (D-B-A) system in the two-photon absorption (TPA).
