One embodiment of the present invention is a method for producing a silicon (Si) and/or germanium (Ge) foil, the method including: dissolving a Si and/or Ge source material in a molten metallic bath at an elevated temperature T2, wherein the density of Si and/or Ge is smaller than the density of the molten metallic bath; cooling the molten metallic bath to a lower temperature T1, thereby causing Si and/or Ge to separate out of the molten metallic bath and to float and grow as a Si and/or Ge foil on a top surface of the molten metallic bath; and separating the floating Si and/or Ge foil from the top surface of the molten metallic bath. |
