Abstract: A method is disclosed for producing high quality semi-insulating silicon carbide crystals in the absence of relevant amounts of deep level trapping elements. The invention includes the steps of heating a silicon carbide crystal having a first concentration of point defect related deep level states to a temperature above the temperatures required for CVD growth of silicon carbide from source gases, but less than the sublimation temperature of silicon carbide under the ambient conditions to thereby thermodynamically increase the number of point defects and resulting states in the crystal, and then cooling the heated crystal to approach room temperature at a sufficiently rapid rate to maintain a concentration of point defects in the cooled crystal that remains greater than the first concentration.

Abstract: Methods for producing silicon carbide crystals, seed crystal holders and seed crystal for use in producing silicon carbide crystals and silicon carbide crystals are provided. Silicon carbide crystals are produced by forcing nucleation sites of a silicon carbide seed crystal to a predefined pattern and growing silicon carbide utilizing physical vapor transport (PVT) so as to provide selective preferential growth of silicon carbide corresponding to the predefined pattern. Seed holders and seed crystals are provided for such methods. Silicon carbide crystals having regions of higher and lower defect density are also provided.

Abstract: A wired pipe system includes a wired pipe segment having a first end and a second end and a first coupler in the first end and a second coupler in the second end. The system also includes a transmission line disposed in the wired pipe segment between the first and second ends. The transmission line includes an inner conductor, an insulating material surrounding the inner conductor, an outer conductor surrounding the insulating material and the inner conductor for at least a portion of a length of the transmission line, the other conductor being formed by deforming around the inner conductor a sheet of material into a substantially tubular member.

Abstract: A tubular connecting arrangement includes, a first tubular having a first shoulder and first threads, a second tubular having a second shoulder and second threads, a seal sealingly engagable to both the first shoulder and the second shoulder, an insert and a sleeve. The insert is attachable to the second tubular and configured to provide radial support to the second tubular. The sleeve threadably engagable with both the first threads and the second threads in response to being rotated in a same direction relative to both the first tubular and the second tubular such that the first shoulder and the second shoulder are moved toward one another to compress the seal therebetween without rotational movement of the first tubular relative to the second tubular.
