Patent ID: 8866245

Claim:
A nuclear battery device, said nuclear battery device comprising: a P-N semiconductor junction, located between a P-type semiconductor layer and an N-type semiconductor layer; two or more contacts; two isotope foils; wherein said two or more contacts are connected to said P-type semiconductor layer and said N-type semiconductor layer; and wherein said P-type semiconductor layer and said N-type semiconductor layer are sandwiched between said two isotope foils; wherein each of said two isotope foils are covered by an oxide layer; wherein each of said oxide layer is connected to a metal contact; a metal-oxide-semiconductor capacitor; wherein said metal-oxide-semiconductor capacitor comprises said sandwiched said P-type semiconductor layer and said N-type semiconductor layer, surrounded on each side by said two isotope foils, surrounded on each side by each of said oxide layer, which is connected on each side by each of said metal contact.
