Superconductivity in heavily boron-doped silicon carbide
2009/1/28· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.

Advances in Silicon Science
Silicon is in the same group of the periodic table as carbon, yet silicon carbide is not another form of diamond or graphite or even amorphous carbon black. It, like most other silicon materials, is unique. This book series represents the journeys of many eminent
Overview of Silicon Carbide
Silicon carbide, due to the close proximity of silicon and carbide on the periodic table, is a highly covalent material that forms tetrahedra that are centered around either carbon or silicon atoms. These tetrahedra form a close-packed structure with half of the tetrahedral sites filled, and occur primarily in the α-SiC and β-SiC phases.

RBS and ERD results showed that the films contain silicon, carbon, hydrogen and small amount of oxygen. FTIR results confirmed the presence of Si-C, Si-H, C-H, and Si-O bonds. From the FTIR spectra the main following vibration frequencies were determined: the band from 2800 to 3000 cm -1 is attributed to stretching vibration of the CHn group in both the sp2 (2880 cm -1 ) and sp3 (2920 cm -1
