Anisotropic Electronic Structure of the Two-Dimensional Electron Gas at the AlOx/KTaO3(110) interface
E. A. Martínez, J. Dai, M. Tallarida +2
Oxide-based two-dimensional electron gases (2DEGs) have generated significant interest due to their potential for discovering novel physical properties. Among these, 2DEGs formed i…
BinPo: An open-source code to compute the band structure of two-dimensional electron systems
Emanuel A. Martínez, Juan I. Beltrán Fínez, Flavio Y. Bruno
We introduce BinPo, an open-source Python code to compute electronic properties of two-dimensional electron systems. Its usage is focused on the ABO perovskite structure based…
Electronic structure of the highly conductive perovskite oxide SrMoO
E. Cappelli, A. Hampel, A. Chikina +12
We use angle-resolved photoemission to map the Fermi surface and quasiparticle dispersion of bulk-like thin films of SrMoO grown by pulsed laser deposition. The electronic self…
A Laser-ARPES View of the 2D Electron Systems at LaAlO3/SrTiO3 and Al/SrTiO3 Interfaces
Siobhan McKeown Walker, Margherita Boselli, Emanuel A. Martínez +3
We have measured the electronic structure of the two-dimensional electron system (2DES) found at the Al/SrTiO3 (Al/STO) and LaAlO3/SrTiO3 (LAO/STO) interfaces by means of laser ang…
A laser-ARPES study of LaNiO3 thin films grown by sputter deposition
Edoardo Cappelli, Willem Tromp, Siobhan McKeown Walker +4
Thin films of the correlated transition-metal oxide LaNiO undergo a metal-insulator transition when their thickness is reduced to a few unit cells. Here, we use angle-resolved…
Band Structure and Spin-Orbital Texture of the (111)-KTaO3 Two-Dimensional Electron Gas
F. Y. Bruno, S. McKeown Walker, S. Riccò +7
Two-dimensional electron gases (2DEGs) in oxides show great potential for discovering new physical phenomena and at the same time hold promise for electronic applications. In this…
High-resolution photoemission on Sr2RuO4 reveals correlation-enhanced effective spin-orbit coupling and dominantly local self-energies
A. Tamai, M. Zingl, E. Rozbicki +17
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr2RuO4 using laser-based angle-resolved photoemission spectroscopy. Ou…
Microfocus laser-ARPES on encapsulated mono-, bi-, and few-layer 1T'-WTe
Irène Cucchi, Ignacio Gutiérrez-Lezama, Edoardo Cappelli +11
Two-dimensional crystals of semimetallic van der Waals materials hold much potential for the realization of novel phases, as exemplified by the recent discoveries of a polar metal…
Observation of out-of-plane spin texture in a SrTiO3 (111) two-dimensional electron gas
Pan He, S. McKeown Walker, Steven S. -L. Zhang +9
We explore the second order bilinear magnetoelectric resistance (BMER) effect in the d-electron-based two-dimensional electron gas (2DEG) at the SrTiO3 (111) surface. We find an ev…
ARPES Studies of Two-Dimensional Electron Gases at Transition Metal Oxide Surfaces
S. McKeown Walker, F. Y. Bruno, F. Baumberger
High mobility two-dimensional electron gases (2DEGs) underpin today's silicon based devices and are of fundamental importance for the emerging field of oxide electronics. Such 2DEG…
Electronic structure of buried LaNiO3 layers in (111)-oriented LaNiO3/LaMnO3 superlattices probed by soft x-ray ARPES
F. Y. Bruno, M. Gibert, S. McKeown Walker +10
Taking advantage of the large electron escape depth of soft x-ray angle resolved photoemission spectroscopy we report electronic structure measurements of (111)-oriented [LaNiO3/La…
