  • Method for forming a multilayer structure
    Patent number: 8470689
    Abstract: The method for forming a multilayer structure on a substrate comprises providing a stack successively comprising an electron hole blocking layer, a first layer made from N-doped semiconductor material having a dopant concentration greater than or equal to 1018 atoms/cm3 or P-doped semiconductor material, and a second layer made from semiconductor material of different nature. A lateral electric contact pad is made between the first layer and the substrate, and the material of the first layer is subjected to anodic treatment in an electrolyte.
    Type: Grant
