Universal Structural Influence on the 2D Electron Gas at SrTiO Surfaces
Eduardo B. Guedes, Stefan Muff, Walber H. Brito +4
The two-dimensional electron gas found at the surface of SrTiO and related interfaces has attracted significant attention as a promising basis for oxide electronics. In order t…
Surface state at evidenced by angle-resolved photoemission spectroscopy and ab initio calculations
Muntaser Naamneh, Abhinav Prakash, Eduardo B. Guedes +5
Perovskite alkaline earth stannates, such as and , showing light transparency and high electrical conductivity (when doped), have become promising candidates for…
Triple point fermions in ferroelectric GeTe
Juraj Krempaský, Laurent Nicolaï, Martin Gmitra +10
Ferroelectric GeTe is unveiled to exhibit an intriguing multiple non-trivial topology of the electronic band structure due to the existence of triple-point and type-II Weyl fermion…
Single spin-polarised Fermi surface in SrTiO thin films
Eduardo B. Guedes, Stefan Muff, Mauro Fanciulli +6
The 2D electron gas (2DEG) formed at the surface of SrTiO(001) has attracted great interest because of its fascinating physical properties and potential as a novel electronic p…
Cooling a polaronic liquid: Phase mixture and pseudogap-like spectra in superconducting
M. Naamneh, M. Yao, J. Jandke +17
Many complex electronic systems exhibit so-called pseudogaps, which are poorly-understood suppression of low-energy spectral intensity in the absence of an obvious gap-inducing sym…
Momentum-Resolved Electronic Structure of the High- Superconductor Parent Compound BaBiO
N. C. Plumb, D. J. Gawryluk, Y. Wang +12
We investigate the band structure of BaBiO, an insulating parent compound of doped high- superconductors, using \emph{in situ} angle-resolved photoemission spectroscop…
