Materials | Free Full-Text | In Situ Doping of Nitrogen in …

Doping of nitrogen is a promising approach to improve the electrical conductivity of 3C-SiC and allow its appliion in various fields. N-doped, <110>-oriented 3C-SiC bulks with different doping concentrations were prepared via halide laser chemical vapour deposition (HLCVD) using tetrachlorosilane (SiCl4) and methane (CH4) as precursors, along with nitrogen (N2) as a dopant. We

Silicon (Si) | AMERICAN ELEMENTS

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.
