Abstract:
The present invention relates to a method of production of graphene comprising the following stages respectively: a stage of deposition of a thin layer comprising amorphous carbon on a substrate; a stage of annealing of said thin layer under photonic and/or electronic irradiation, by which a layer comprising graphene is obtained.
Abstract:
The invention relates to a process for producing at least one air gap in a microstructure, which comprises: 1) the supply of a microstructure comprising at least one gap filled with a sacrificial material that decomposes starting from a temperature θ1, this gap being delimited over at least one part of its surface by a non-porous membrane, composed of a material that forms a matrix and of a pore-forming agent that decomposes at a temperature θ2

Abstract:
Provided a method for producing an oriented-porosity dielectric material on a substrate. The method includes depositing a vapor phase on a substrate of a composite layer comprising a material forming a matrix and a compound comprising chemical groups capable of being oriented under the effect of an electromagnetic field and/or photonic radiation; treating the composite layer to obtain the cross-linking of the material forming a matrix; and subjecting the substrate coated with the composite layer to an electromagnetic field and/or a photonic radiation.
