Spin-dependent recombination in Czochralski silicon containing oxide precipitates

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, ...

Characterization of Cu and Ni precipitates in n- and p-type Czochralski-grown silicon by photoluminescence

Photoluminescence (PL) images and micro-PL maps were taken on nand p-type, Cuand Ni-doped monocrystalline silicon wafers, in which the Ni and Cu had precipitated during ingot growth. Markedly different distributions of the precipitates were observed in the nand p-type samples: in the n-type Cu-doped samples, a particle-lean ring structure was observed, dividing the sample into a central region ...

Spin-dependent Resonant Tunneling in Ferromagnet-Oxide-Silicon Structures

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...

Numerical Modeling of Czochralski Silicon Crystal Growth

Modeling of heat transfer is presented for the entire Czochralski Si-growth furnace. The axisymmetric steady-state approach with moving computational grids is used. Melt turbulent flow, inert gas flow, heat transfer in solid parts, and radiative heat transfer in the system are considered. The Reynolds-averaged Navier-Stokes equations written with the Boussinesq approximation and the energy equa...
