A first set of contacts is disposed in contact with the surface along a first axis, and a second set of contacts is disposed in contact with the surface along a second axis transverse to the first axis. An insulating layer is disposed on the surface. A metal control field plate is disposed on the insulating layer and is coupleable to a voltage source to control the accumulation of charge carriers at the surface of the active layer to vary the resistance of the active layer. Also, a method is provided for reducing null offset in a Hall-effect element. The method includes the steps of providing an isolating layer, disposing an active layer of a first electrical conductivity type on the isolating layer, the active layer having a surface, disposing a first set of contacts on the surface along a first axis, disposing a second set of contacts on the surface along a second axis transverse to the first axis; and disposing an insulating layer on the surface. A voltage is applied across the insulating layer to control the accumulation of charge carriers at the surface to vary the resistance of the active layer.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E401671-T1: [Translated] HALL EFFECT ELEMENT WITH INTEGRATED DEVIATION CONTROL AND METHOD FOR OPERATING SUCH AN ELEMENT FOR REDUCING THE ZERO POINT DEVIATION on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E401671-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/muiy-b4yh", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/muiy-b4yh", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E401671-T1: [Translated] HALL EFFECT ELEMENT WITH INTEGRATED DEVIATION CONTROL AND METHOD FOR OPERATING SUCH AN ELEMENT FOR REDUCING THE ZERO POINT DEVIATION"}
