Latest Patents: Jean Chevrier holds a patent for an "Epitaxial structure with increased piezoelectric effect and a surface." This invention involves an epitaxial structure where a constraint imposed by forced epitaxy leads to an increase in the piezoelectric effect of a group of layers. The structure utilizes a semi-insulating substrate made from a first material, on which a layer of a second material is deposited. The two materials are in crystalline mesh parameter disharmony, creating a constraint that enhances the piezoelectricity of the layer. Additionally, the structure allows for the integration of two transducers, such as transistors, on or adjacent to it.
