Inducing - and -type thermoelectricity in oxide superlattices by strain tuning of orbital-selective transport resonances
Benjamin Geisler, Rossitza Pentcheva
By combining first-principles simulations including an on-site Coulomb repulsion term and Boltzmann theory, we demonstrate how the interplay of quantum confinement and epitaxial st…
Temperature-dependent spin-resolved electronic structure of EuO thin films
Tristan Heider, Timm Gerber, Okan Köksal +10
The electronic structure of the ferromagnetic semiconductor EuO is investigated by means of spin- and angle-resolved photoemission spectroscopy (spin-ARPES) and density functional…
Confinement- and strain-induced enhancement of thermoelectric properties in LaNiO/LaAlO superlattices
Benjamin Geisler, Rossitza Pentcheva
By combining ab initio simulations including an on-site Coulomb repulsion term and Boltzmann theory, we explore the thermoelectric properties of (LaNiO)/(LaAlO)(001…
Design of Chern Insulating Phases in Honeycomb Lattices
W. E. Pickett, K. -W. Lee, R. Pentcheva
The search for robust examples of the magnetic version of topological insulators, referred to as quantum anomalous Hall insulators or simply Chern insulators, so far lacks success.…
Unexpected Termination Switching and Polarity Compensation in LaAlO3/SrTiO3 heterostructures
Guneeta Singh-Bhalla, Pim B. Rossen, Gunnar K. Palsson +12
Polar crystals composed of charged ionic planes cannot exist in nature without acquiring surface changes to balance an ever-growing dipole. The necessary changes can manifest struc…
