The Dirac semimetal RuO2: From topology to functionality (C10)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 258499086

This project studies the functional Dirac semi-metal RuO2, a binary model oxide whose crystal symmetry-induced band structure topology produces a complex Fermi surface composed of Dirac nodal lines and a flat band surface state. We will employ STM/STS, spin-ARPES, and magneto-transport experiments to establish the link between fundamental band structure topology, electron correlation and spin-splitting phenomena in RuO2.
