Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…
Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet
Sajid Husain, Maya Ramesh, Xinyan Li +21
Since Felix Bloch's introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, par…
Inverse Rashba-Edelstein THz emission modulation induced by ferroelectricity in CoFeB/PtSe2/MoSe2//LiNbO3 systems
S. Massabeau, O. Paull, A. Pezo +10
Spintronic Terahertz emitters, based on optically triggered spin-to-charge interconversion processes, have recently emerged as novel route towards compact and efficient THz sources…
Polarization boost and ferroelectricity down to one unit cell in layered Carpy-Galy LaTiO thin films
Elzbieta Gradauskaite, Anouk S. Goossens, Xiaoyan Li +4
Layered perovskite-based compounds offer a range of unconventional properties enabled by their naturally anisotropic structure. While most renowned for the superconductivity observ…
Electronic bandstructure of superconducting KTaO3 (111) interfaces
Srijani Mallik, Börge Göbel, Hugo Witt +17
Two-dimensional electron gases(2DEGs)based on KTaO3 are emerging as a promising platform for spin-orbitronics due to their high Rashba spin-orbit coupling (SOC) and gate-voltage tu…
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…
