For the first time, inductors were integrated on porous silicon carbide to study the effect of this substrate on radio-frequency (RF) performances. n-Type heavily doped 4H-SiC substrates were anodized in an HF-based electrolyte to produce 6- and 15--thick porous layers.-thick porous layers.
To manufacture Reaction Bonded Silicon Carbide (RBSC), Silicon is infiltrated into a pre-formed silicon carbide/carbon powder green body which is then fired. This gives rise to around 10% free silicon, which fills the pores. The resulting microstructure has low
PATENT CLAIMS 1. Silicon carbide sinter product characterized by the fact that it is composed essentially of lengthy and/or table-like grains of an SiC-AIN fix solution, consisting primarily of 2 to 20% by weight of Al, 0.2 to 10% by weight of N, 0.2 to 5% by weight
2014/8/6· A review of recent advances in the field of epitaxial growth of SiC films on Si by means of a new method of epitaxial substitution of film atoms for substrate atoms has been presented. The basic statements of the theory of the new method used for synthesizing SiC on Si have been considered and extensive experimental data have been reported. The elastic energy relaxation mechanism …

The production of silicon carbide is know to generate contaminants suspected of affecting the incidence of lung cancer in exposed workers. This project, incorporating retrospective cohort and case-control studies, will determine whether workers exposed to silicon carbide exhibit excess lung cancer mortality compared to unexposed individuals.
Si is diamond structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Si is bonded to four equivalent Si atoms to form corner-sharing SiSi4 tetrahedra. All Si–Si bond lengths are 2.37 Å.

Both 3C-SiC:B and 6H-SiC:B reveal type-I superconductivity with a critical temperature T c =1.5 K. On the other hand, Al-doped 3C-SiC (3C-SiC:Al) shows type-II superconductivity with T c =1.4 K. Both SiC:Al and SiC:B exhibit zero resistivity and diamagnetic susceptibility below T c with effective hole-carrier concentration n higher than 10 20 cm -3 .
Extreme temperature measurements of Ni/Ti/Al contacts to p-type SiC (N-a = 1.10(18)cm(-3)), with a specific contact resistivity rho(c) = 6.75.10(-4) Omega cm(2) at 25 degrees C, showed a five time increase of the specific contact resistivity at -40 degrees C (rho(c) = 3.16.10(-3) Omega cm(2)), and a reduction by almost a factor 10 at 500 degrees C (rho(c) = 7.49.10(-5) Omega cm(2)).
