Visualizing giant ferroelectric gating effects in large-scale WSe/BiFeO heterostructures
Raphaël Salazar, Sara Varotto, Céline Vergnaud +13
Multilayers based on quantum materials (complex oxides, topological insulators, transition-metal dichalcogenides, etc) have enabled the design of devices that could revolutionize m…
Direct visualization of Rashba-split bands and spin/orbital-charge interconversion at KTaO interfaces
Sara Varotto, Annika Johansson, Börge Göbel +10
Rashba interfaces have emerged as promising platforms for spin-charge interconversion through the direct and inverse Edelstein effects. Notably, oxide-based two-dimensional electro…
Breakdown of bulk-projected isotropy in surface electronic states of topological Kondo insulator SmB(001)
Yoshiyuki Ohtsubo, Toru Nakaya, Takuto Nakamura +4
The topology and spin-orbital polarization of two-dimensional (2D) surface electronic states have been extensively studied in this decade. One major interest in them is their close…
