Very high efficiency, miniaturized, long-lived alpha particle power source using diamond devices for extreme space environments |
| abstract |
A power source converts α-particle energy into electricity by coulomb collision in doped diamond films. Alpha particle decay from curium-244 creates electron-hole pairs by freeing electrons and holes inside the crystal lattice in N- and P-doped diamond films. Ohmic contacts provide electrical connection to an electronic device. Due to the built-in electric field at the rectifying junction across the N- and P-doped diamond films, the free electrons are constrained to traveling in generally one direction. This one direction then supplies electrons in a manner similar to that of a battery. The radioactive curium layer may be disposed on diamond films for even distribution of α-particle radiation. The resulting power source may be mounted on a diamond substrate that serves to insulate structures below the diamond substrate from α-particle emission. Additional insulation or isolation may be provided in order to prevent damage from α-particle collision. N-doped silicon may be used instead of N-doped diamond. |
