Abstract:
1. A method of constructing an amorphous solid-state high energy-density micro radioisotope power source device; said method comprising: directly mixing at least one semiconductor material with at least one radioisotope material to provide a pre-voltaic semiconductor mixture; subsequently depositing the pre-voltaic semiconductor mixture into a micro chamber formed in a bottom portion of a high energy-density micro radioisotope power source device, the bottom portion of the high energy-density micro radioisotope power source device including a first electrode disposed in a bottom of the micro chamber; subsequently disposing a top portion of the high energy-density micro radioisotope power source device onto the bottom portion of the high energy-density micro radioisotope power source device, covering the micro chamber, to provide an assembled body of the high energy-density micro radioisotope power source device, the top portion of the high energy-density micro radioisotope power source device including a second electrode disposed at a top of the micro chamber; subsequently heating the assembled body to a temperature at which the pre-voltaic semiconductor mixture will liquefy within the micro chamber such that atoms of the at least one semiconductor material will chemically bind with atoms of the at least one radioisotope material and provide a liquid state composite; and subsequently cooling the assembled body and liquid state composite such that liquid state composite solidifies to provide a solid-state composite voltaic semiconductor, and thereby providing a solid-state high energy-density micro radioisotope power source device.
