Abstract
Official abstract text for this publication.
A passive radiofrequency microelectronic components for an integrated circuit which includes a dielectric substrate and at least one metal conductive layer positioned on said substrate. The conductive layer including at least one first metal conductive portion and a second metal conductive portion separated by an insulation. A microelectronic component according to the invention includes at least one graphene layer positioned so that a radiofrequency or hyperfrequency signal crosses said at least one graphene layer when it is transmitted between said first metal conductive portion and said second metal conductive portion, said graphene layer being able, when it is subject to an electric potential, to transmit said radiofrequency or hyperfrequency signal along a first direction and to attenuate said radiofrequency or hyperfrequency signal along a second direction opposite to said first direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A passive radiofrequency microelectronic component for an integrated circuit forming a micro-switch comprising a dielectric substrate and at least one metal conductive layer positioned on said substrate, said conductive layer including at least one first metal conductive portion and a second metal conductive portion separated by an insulation, comprising: at least one graphene layer positioned so that a radiofrequency or hyperfrequency signal crosses said at least one graphene layer when it is transmitted between said first metal conductive portion and said second metal conductive portion, said graphene layer being able, when it is subject to an electric potential, to transmit said radiofrequency or hyperfrequency signal along a first direction and to attenuate said radiofrequency or hyperfrequency signal according to a second direction opposite to said first direction; and a flexible metal membrane able to establish contact in said first metal conductive portion and said second metal conductive portion, the first metal conductive portion being covered with a dielectric layer, wherein said graphene layer is positioned in contact with said dielectric layer. 2. The radiofrequency microelectronic component according to claim 1 , comprising a plurality of alternating dielectric and graphene layers. 3. The radiofrequency microelectronic component according to claim 1 , wherein a said graphene layer consists of a sheet of carbon crystals with a mono-atomic thickness. 4. The radiofrequency micro-electronic component according to claim 1 , wherein said graphene layer is of the same dimensions in width and in length as said dielectric layer.
