Continuous Silicon Carbide Fibers

Preparation and Characterization of Continuous Fe-Containing Silicon Carbide Radar Absorbing Fibers from Precursor-Based Processing

A new polymer polyferrocarbosilane (PFCS) was synthesized using polydimethylsilane and ferrocene as the raw materials. The polymer was then melt-spun into continuous PFCS fibers, cured in air and heat-treated in a nitrogen atmosphere up to 1300 , a kind of Fe-containing SiC fibers were finally obtained. The SiC(Fe) ceramic fibers were combined with epoxy resin and a structural material was prep...

Silicon Nitride and Silicon Carbide

Boron carbide/n-silicon carbide heterojunction diodes

Silicon carbide microdisk resonator.

We demonstrate a silicon carbide (SiC) microdisk resonator with an intrinsic optical quality factor of 6.19×10(3), fabricated on the 3C-SiC-on-Si platform. We characterize the temperature dependence of the cavity resonance and obtain a thermo-optic coefficient of 2.92×10(-5)/K for 3C-SiC. Our simulations show that the device exhibits great potential for cavity optomechanical applications.

Silicon Carbide Neutron Detectors

The potential of Silicon Carbide (SiC) for use in semiconductor nuclear radiation detectors has been long recognized. In fact, the first SiC neutron detector was demonstrated more than fifty years ago (Babcock, et al., 1957; Babcock & Chang, 1963). This detector was shown to be operational in limited testing at temperatures up to 700 oC. Unfortunately, further development was limited by the poo...
