Cubic silicon carbide as a potential photovoltaic material

For the ion implanted samples the crystal quality was maintained even after high implantation doses and subsequent annealing. The same was true for the samples grown with pre-doped source material, even with a high concentration of boron impurities. We present optical emission and absorption properties of as-grown and boron implanted 3C-SiC.

[0810.0056] Superconductivity in heavily boron-doped

2009-11-13 · Recently, we discovered superconductivity in a closely related system: heavily-boron doped silicon carbide (SiC:B). The sample used for that study consists of cubic and hexagonal SiC phase fractions and hence this lead to the question which of them participates in the superconductivity.

2019-3-20 · Silica, as sand, is a principal ingredient of glass--a material with excellent mechanical, optical, thermal, and electrical properties. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.

cubic and hexagonal SiC phase fractions and hence this led to the question which of them participated in the superconductivity. Here we studied a hexagonal SiC sample, free from cubic SiC phase by means of x-ray diffraction, resistivity, and ac susceptibility.

2013-9-17 · Swedish Cubic SiC Attracts Norwegian Solar Cell Research. Cubic SiC may host a new approach for a highly efficient solar cell material. Theory has shown that cubic SiC may act as a highly efficient solar cell material if doped with boron. This has not been explored since this semiconductor material is challenging to produce.

2014-7-1 · Bulk carbon is important because it can form carbon-related defects, such as SiC inclusions. Bulk oxygen is important in boron-doped silicon because a BOx defect can degrade cell efficiency. Boron and phosphorus are common dopants in solar Si wafers, and are difficult to measure directly in solar Si wafers, especially in highly compensated silicon.

Effect of Weight Loss on Liquid‐Phase‐Sintered Silicon

The SiC powder compacts contained 7.5 wt% eutectic composition of Y 2 O 3 –Al 2 O 3 to promote liquid‐phase sintering. A weight loss of 1–11 wt% was observed during sintering, depending on the sintering temperature and sintering time. The weight loss severely influenced the final density and the microstructure of the SiC ceramics.

Pan Stanford Publishing - Carbon-based

Before 2004, the superconducting transition temperature (Tc) of the carbon-based SCs was below 1 K, except for fullerene clusters. On the other hand, in 2004, a Russian group discovered that highly boron-doped diamond can be an SC at Tc = 4 K. Then, next year, a Caridge group found that calcium-intercalated graphite can be an SC with Tc = 11.5 K.
