Silicon carbide is an attractive candidate for high power and high temperature electronics due to its inherent high thermal conductivity, large saturated drift velocity, high breakdown strength and large bandgap. A review of the material properties w

This report summarizes a program for which the overall goal was improving the understanding of the material and device factors that limit the performance of solar cells fabricated from dendritic web silicon. An analytical model for crystal defect gen

Numerical calculation of 111-plane 110-line slip activity in silicon web crystals generated by thermal stresses is in good agreement with etch pit patterns and X-ray topographic data. The data suggest that stress redistribution effects are small and

Significant progress has been made in our understanding of the web growth process. Thermal models have been developed that accurately predict the thermally generated stresses in the web crystal which, if too high, cause the crystal to degenerate. The

We have recently produced the widest silicon web crystal 47mm, and demonstrated the highest web area output rate to date, 27cm/sup 2//min. The latter result is particularly significant. Web growth at this rate sustained by means of Melt replenishment

The dendritic web growth process is a crystal growth technique which produces thin, long, ribbons of essentially single-crystalline material. The ribbon morphology results from an interaction of crystallographic and surface tension forces so that pos

A total of 154 experimental silicon web growth runs were performed during the first year of this program. Each of the web crystals grown was characterized dimensionally, showing that the average width per run had increased by 60% as compared to the s

Thirty-five (35) furnace runs were carried out during this quarter, of which 25 produced a total of 120 web crystals. Lengths in excess of two meters and widths over 27 mm were achieved. A variety of lid and susceptor configurations have been used to

Two types of design concepts were evaluated with the thermal models: (1) a vertical thermal element which modifies both the temperature profile in the web as well as the convective gas flow near the web; and (2) a thinner lid configuration in which t
