Constitutional Supercooling in Czochralski Growth οf Heavily Doped Silicon Crystals

Superconductivity in heavily boron-doped silicon carbide.

The discoveries of superconductivity in heavily boron-doped diamond in 2004 and silicon in 2006 have renewed the interest in the superconducting state of semiconductors. Charge-carrier doping of wide-gap semiconductors leads to a metallic phase from which upon further doping superconductivity can emerge. Recently, we discovered superconductivity in a closely related system: heavily boron-doped ...

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...

Near-infrared free carrier absorption in heavily doped silicon

Superconductivity of hexagonal heavily-boron doped silicon carbide

In 2004 the discovery of superconductivity in heavily boron-doped diamond (C:B) led to an increasing interest in the superconducting phases of wide-gap semiconductors. Subsequently superconductivity was found in heavily boron-doped cubic silicon (Si:B) and recently in the stochiometric ”mixture” of heavily boron-doped silicon carbide (SiC:B). The latter system surprisingly exhibits type-I super...
