Micro-cantilever testing of diamond - silicon carbide interfaces in silicon carbide bonded diamond materials produced by reactive silicon infiltration

Titanium Impurities in Silicon, Diamond, and Silicon Carbide

Since transition metal impurities affect the electronic and optical properties of semiconductors [1], it is important to understand the role of such unavoidable impurities on those properties. At the same time, transition metals in semiconductors can be used in other unusual situations. The energy levels related to transition metal impurities are aligned with respect to each other for the same ...

Single Point Diamond Turning of CVD coated Silicon Carbide

Scratching experiments, using diamond styli and single point diamond tools, were performed to simulate Single Point Diamond Turning (SPDT). The results of these experiments were used to determine if a ductile response is possible, and then to determine the critical depth of cut or penetration depth for the ductile to brittle transition (DBT). The depths of the scratches produced at different lo...

Properties of nanostructured diamond-silicon carbide composites sintered by high pressure infiltration technique

A high-pressure silicon infiltration technique was applied to sinter diamond–SiC composites with different diamond crystal sizes. Composite samples were sintered at pressure 8 GPa and temperature 2170 K. The structure of composites was studied by evaluating x-ray diffraction peak profiles using Fourier coefficients of ab initio theoretical size and strain profiles. The composite samples have pr...

High Performance Power Diodes on Silicon Carbide and Diamond

Silicon Carbide and diamond Schottky barrier diodes (SBD) with an original and high efficiency termination are presented. The influences of termination parameters on the diodes electrical performance are investigated for both punch-through (PT) and non punch-through (nPT) structures by simulations. Design guidelines, based on simple analytical expressions, for ideal SBDs are included. Electrica...
