Publication number: 20230238328Abstract: Described herein are devices and methods that utilize three-dimensional topological semimetals (including Dirac, Weyl and nodal line) that may be useful in advanced electronic devices. The Fermi level in three dimensional topological semimetals can be significantly shifted in energy when forming a heterojunction with a semiconductor or metal. This has unintended and sometimes negative consequences for device performance. Described herein are designs and methods to modify the heterostructures to either suppress Fermi level movement or to produce an intentional shift to allow for the use of these improved semimetal devices.Type: ApplicationFiled: January 20, 2023Publication date: July 27, 2023Inventors: Kirstin ALBERI, Anthony D. RICE, Brian Darrius FLUEGEL, Choong Hee LEE
