Patent number: 11450804Abstract: Subject matter disclosed herein may relate to construction of a correlated electron material (CEM) device. In particular embodiments, after formation of a film comprising layers of a transition metal oxide (TMO) material and a dopant, at least a portion of the film may be exposed to an elevated temperature. Exposure of the at least a portion of the film to the elevated temperature may continue until the atomic concentration of the dopant within the film is reduced, which may enable operation of the film as a correlated electron material CEM exhibiting switching of impedance states.Type: GrantFiled: July 23, 2020Date of Patent: September 20, 2022Assignee: CERFE LABS, INC.Inventors: Carlos Alberto Paz de Araujo, Jolanta Bozena Celinska, Lucian Shifren

Patent number: 11011701Abstract: Subject matter disclosed herein may relate to fabrication of a correlated electron material (CEM) switch. In embodiments, processes are described in which conductive traces may be formed on or over an insulating material. Responsive to forming voids in the insulating material, localized portions of the conductive traces in contact with the voids may be exposed to gaseous oxidizing agents, which may convert the localized portions of the conductive traces to a CEM. In embodiments, an electrode material may be deposited within the voids to contact the localized portion of conductive trace converted to the CEM.Type: GrantFiled: January 28, 2019Date of Patent: May 18, 2021Assignee: Cerfe Labs, Inc.Inventors: Carlos Alberto Paz de Araujo, Jolanta Bozena Celinska, Kimberly Gay Reid, Lucian Shifren

Patent number: 11005039Abstract: A correlated electron material device is described to comprise a conductive substrate and a layer of a correlated electron material disposed over the conductive substrate. The layer of correlated electron material may comprise a metal rich transition or other metal compound, and at least a portion of anion vacancies within the metal rich transition or other metal compound are occupied by an electron back-donating extrinsic ligand for the metal rich transition or other metal compound. Under certain conditions, the electron back-donating extrinsic ligand occupying anion vacancies may be activated so as to impart particular switching characteristics in the correlated electron material device.Type: GrantFiled: January 23, 2020Date of Patent: May 11, 2021Assignee: Cerfe Labs, Inc.Inventors: Carlos Alberto Paz de Araujo, Jolanta Bozena Celinska, Lucian Shifren
