Resonant x-ray absorption and scattering study of classical and oxide-based topological insulators (C04)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2015 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 258499086

In this project we will use resonant x-ray scattering to study two main topics: (i) Taking advantage of the probing depth and the nm depth resolution of our method, we plan to study the interaction of incorporated Mn, Cr and Fe impurities with the gapless surface states in HgTe, ¿-Sn, and (Bi,Sb)2(Se,Te)3. (ii) We will contribute to the realization of a topological insulator in correlated transition metal-oxides which is expected on theoretical grounds in titanate and nickelate films of proper crystallographic orientation.
