Latest Patents

Marc Reynaud holds a patent for "Systems and methods for integrating a-axis oriented barium titanate thin films on silicon (001) via strain control." This patent describes various embodiments that enable the growth of a-axis oriented barium titanate (BTO) films by inserting a relaxed strain control layer. This layer has a larger lattice constant than the c-axis of BTO and a similar thermal expansion mismatch. As a result, in-plane tensile stress allows BTO to grow with its ferroelectric polarization in-plane. Some embodiments of this technology enable the immediate growth of BTO films on silicon with a-axis orientation, eliminating the need for thick layers for relaxation. The technology also allows for the growth of BTO in-plane with minimal dislocation density confined to the interface region.
