  • Direct energy conversion devices with a substantially continuous depletion region and methods thereof
    Publication number: 20080006891
    Abstract: An energy conversion device includes a plurality of pores formed within a substrate and a junction region disposed within each of the plurality of pores where each of the junction regions has a depletion region. Each of the plurality of pores defines an opening size in the substrate and a spacing from adjacent pores so that the depletion regions of each of the pores are at least substantially in contact with the depletion region of the pores which are adjacent.
    Type: Application
    Filed: October 25, 2005
    Publication date: January 10, 2008
    Inventors: Larry Gadeken, Wei Sun, Nazir Kherani, Philippe Fauchet
  • METHODS OF MAKING ENERGY CONVERSION DEVICES WITH A SUBSTANTIALLY CONTIGUOUS DEPLETION REGIONS
    Publication number: 20070134840
    Abstract: A method of making an energy conversion device includes forming a plurality of pores within a substrate and forming a junction region within each of the plurality of pores. Each of the junction regions has a depletion region and each of the plurality of pores defines an opening size in the substrate and a spacing from adjacent pores so that the depletion regions of each of the pores is at least substantially in contact with the depletion region of the pores which are adjacent.

  • Apparatus and method for generating electrical current from the nuclear decay process of a radioactive material
    Patent number: 6949865
    Abstract: An apparatus and method for generating electrical power from the decay process of a radioactive material is disclosed, wherein a volume of radioactive material and a junction region are enclosed in a cell. The junction region is formed by appropriate construction of a number of p-type and n-type dopant sites. At least a portion of one of the junction regions is disposed within a porous region having an aspect ratio of greater than about 20:1, and disposed at an angle of greater than about 55° measured relative to the surface area in which it is formed. The dimensions and shapes of the macroporous regions and the improved junction region surface area available for collecting charged particles emitted during a radioactive decay series permit an improved current to be derived from the apparatus than would otherwise be expected given its external dimensions.
    Type: Grant
