Thermal Conductivity of Pure and Impure Silicon, Silicon …
20/7/2004· In impure SiC the phonons are also stered by the electrically active impurities Al and N. These impurities reduce the K of SiC in much the same way that B and P impurities do in Si. The N impurities in natural diamonds also reduce their K below that of ideally pure diamond, but the effect is rather different since N is not electrically active.

Structural Properties of Liquid SiC during Rapid …
The rapid solidifiion of liquid silicon carbide (SiC) is studied by molecular dynamic simulation using the Tersoff potential. The structural properties of liquid and amorphous SiC are analyzed by the radial distribution function, angular distribution function, coordination nuer, and visualization technology. Results show that both heteronuclear and homonuclear bonds exist and no atomic

Steering SiC MOSFET for efficient, compact, reliable …
A new compound semiconductor material, silicon carbide (SiC), provides several advantages over silicon for making these power switching MOSFETs but, it is extremely hard. SiC has ten times (10x) the breakdown electric field strength, three times (3x) the bandgap, and enables a wide range of p- and n-type control required for device construction.
