Nanostructured current sources based on carbon nanotubes excited by β radiation

An analysis of available and promising developments is carried out in the field of power elements based on β decay. The possible fabrication technologies are described, and the efficiency of the power sources manufactured with them is calculated. The possibility of designing a self-charging supercapacitor based on carbon nanotubes is considered with the use of 63Ni and 14C isotopes, and theoretical calculation confirms the promising nature of this line of research.
