Character of Doped Holes in NdSrNiO
Tharathep Plienbumrung, Michael Schmid, Maria Daghofer +1
We investigate charge distribution in the recently discovered high- superconductors, layered nickelates. With increasing value of charge-transfer energy we observe the expecte…
Coexistence of trapped and free excess electrons in SrTiO3
Xianfeng Hao, Zhiming Wang, Michael Schmid +2
The question whether excess electrons in SrTiO3 form free or trapped carriers is a crucial aspect for the electronic properties of this important material. This fundamental ambigui…
A direct view at excess electrons in TiO rutile and anatase
Martin Setvin, Cesare Franchini, Xianfeng Hao +6
A combination of Scanning Tunneling Microscopy/Spectroscopy and Density Functional Theory (DFT+U) is used to characterize excess electrons in TiO rutile and anatase, two protot…
