Patent ID: 8134216

Claim:
A nuclear battery, said nuclear battery comprising: a P-N semiconductor junction, located between a P-type semiconductor layer and an N-type semiconductor layer; one or more contacts; and at least three isotope foils; wherein said at least three isotope foils comprises a first isotope foil, a second isotope foil, and a third isotope foil; wherein said first isotope foil is positioned parallel to said P-N semiconductor junction; said first isotope foil is connected to only one of said P-type semiconductor layer or said N-type semiconductor layer; said second isotope foil and said third isotope foil are parallel to each other; said second isotope foil and said third isotope foil are perpendicular to said first isotope foil; said second isotope foil and said third isotope foil are perpendicular to said P-N semiconductor junction; said second isotope foil and said third isotope foil are connected to both of said P-type semiconductor layer and said N-type semiconductor layer; wherein said one or more contacts are connected to at least one of said P-type semiconductor layer or said N-type semiconductor layer.
