Abstract
A diamond-based high power nuclear voltaic power source is described. The device is designed to supply electrical power by converting radiation energy from radioisotopes into electric power. In the process of extracting the electric power, the structure of the power source is used to assist the electric charge out from the diamond compartment of the device at high efficiency and high power.
Claims18
A nuclear power source comprising:
- at least one radioisotope;
- at least one diamond-based charge generator comprising an ohmic contact layer, a P+-type diamond layer on a side of the ohmic contact layer, a P-type diamond layer on a side of the P+-type diamond layer opposite the ohmic contact layer, a Schottky contact layer on a side of the P-type diamond layer opposite the P+-type diamond layer, an insulator layer on a side of the Schottky contact layer opposite the P-type diamond layer, and an end contact layer on a side of the insulator layer opposite the Schottky contact layer;
- at least one electric contact electrically connected to the at least one diamond-based charge generator;
- and
- a radiation shield that encompasses the at least one radioisotope, the at least one diamond-based charge generator, and the at least one electric contact,
- wherein the radiation shield comprises Single-Crystalline Diamond (SCD), Polycrystalline Diamond (PCD), Diamond-Like Carbon (DLC), Nano-Diamonds (ND), diamondoids, sintered diamond, amorphous diamond, or combinations thereof.
