First-Principles Study of Adsorption Properties of NO2 on
To explore a novel sensor to detect the presence of nitrogen dioxide (NO2), we investigate reactivity of boron-doped (B-doped) single-walled (8,0) silicon carbide nanotube (SiCNT) with NO2. Based on density functional theory, the structure and electronic properties of the B-doped SiCNT with and without the adsorption of NO2 molecule have been calculated.

Can Silicon Carbide Nanotubes Sense Carbon Dioxide
Mar 05, 2009· Detection of carbon dioxide (CO2) is very important in environmental, biological, and industrial processes. Recent experiment showed that carbon nanotubes can act as chemical sensors for detecting certain gaseous molecules such as NH3, NO2, and O2. Unfortunately, the intrinsic stability of CO2 makes its sensing by CNTs unsuccessful due to the rather weak adsorption energy on the tube …

Superconductivity in heavily boron-doped silicon carbide
Abstract The discoveries of superconductivity in heavily boron-doped diamond in 2004 and silicon in 2006 have renewed the interest in the superconducting state of semiconductors. Charge-carrier doping of wide-gap semiconductors leads to a metallic phase from which upon further doping superconductivity can emerge. Recently, we discovered superconductivity in a closely related system: heavily
