  • Method for making semi-conductor nanocrystals oriented along a predefined direction
    Patent number: 8697548
    Abstract: A method for making a semi-conductor nanocrystals, including at least the steps of: making a stack of at least one uniaxially stressed semi-conductor thin layer and a dielectric layer, annealing the semi-conductor thin layer such that a dewetting of the semi-conductor forms, on the dielectric layer, elongated shaped semi-conductor nanocrystals oriented perpendicularly to the stress axis.
    Type: Grant
    Filed: May 4, 2012
    Date of Patent: April 15, 2014
    Assignees: Commissariat a l'energie atomique et aux energies alternatives, Centre National de la Recherche Scientifique
    Inventors: Lukasz Borowik, Jean-Charles Barbe, Ezra Bussmann, Fabien Cheynis, Frédéric Leroy, Denis Mariolle, Pierre Müller
  • Method for making semi-conductor nanocrystals
    Patent number: 8647957
    Abstract: A method for making semi-conductor nanocrystals, including at least the steps of: forming solid carbon chemical species on a semi-conductor thin layer provided on at least one dielectric layer, the dimensions and the density of the carbon chemical species formed on the semi-conductor thin layer being a function of the desired dimensions and density of the semi-conductor nanocrystals; annealing the semi-conductor thin layer, performing a dewetting of the semi-conductor and forming, on the dielectric layer, the semi-conductor nanocrystals.
