Spin-dependent recombination in GaAsN solid solutions

Spin-dependent polaron recombination in conjugated polymers.

We simulate the interchain polaron recombination process in conjugated polymer systems using a nonadiabatic molecular dynamics method, which allows for the coupled evolution of the nuclear degrees of freedom and multiconfigurational electronic wavefunctions. Within the method, the appropriate spin symmetry of the electronic wavefunction is taken into account, thus allowing us to distinguish bet...

Spin–dependent recombination – an electronic readout mechanism for solid state quantum computers

It is shown that coherent spin motion of electron–hole pairs localized in band gap states of silicon can influence charge carrier recombination. Based on this effect, a readout concept for silicon based solid–state spin–quantum computers as proposed by Kane is suggested. The P quantum bit (qbit) is connected via hyperfine coupling to the spin of the localized donor electron. When a second local...

Spin dependent recombination in F&doped silicon p-n junctions

Electrically detected magnetic resonance experiments showing spin dependent recombination in commercial p-n diodes are presented. The observed anisotropy in the g values along with the marked shift from the free electron g-value point to a metal-vacancy complex. Deep level transient spectroscopy reveals the presence of the Pt acceptor level (O/ ) at EC 0.23 eV and the donor level ( + 10) at E, ...

Using one spin-transition to trigger another in solid solutions of two different spin-crossover complexes.

Phase-pure solid solutions of [Co(terpy)(2)][BF(4)](2) and [M(bpp)(2)][BF(4)](2) (M = Fe or Ru, bpp = 2,6-dipyrazol-1-ylpyridine) have been prepared. The spin-state of the [Co(terpy)(2)](2+) dopant is modulated by the spin-state of the [Fe(bpp)(2)](2+) centres in the iron-containing materials.
