Thermal Donor Generation in Boron- and Aluminium-Doped Czochralski Silicon

Intentional thermal donor activation in magnetic Czochralski silicon

We have made a quantitative study about the thermal activation of thermal donors in high resistivity magnetic Czochralski silicon. The thermal donor activation has been performed through a thermal treatment at 430 1C up to a total time of 80min. The space charge density after each annealing step has been extracted from capacitance–voltage measurements. If the starting material is boron-doped p-...

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 ...
