Soft-X-ray ARPES: k-resolved electronic structure of 3D materials, buried interfaces and impurities

ARPES is the unique tool to explore electronic structure of solid-state systems resolved in electron momentum k. Pushing this technique into the soft-X-ray energy range (SX-ARPES) extends its applications from surface physics towards 3D crystal systems, buried interfaces and impurity systems. These spectroscopic abilities results from enhancement of the photoelectron escape depth and a possibility of resonant photoexcitation delivering the elemental and chemical state specificity [1]. 3D materials. The applications to 3D systems are based on sharp definition of surface-perpendicular momentum resulting from the enhanced photoelectron delocalization. An example is the perovskite La1 xSrxMnO3 where the experimental Fermi surface reveals "shadow" contours, which manifest the rhombohedral structural distortion affecting interplay of the double-exchange itineracy and polaronic self-localization [2]. Other examples include polaronic physics in Ce-doped CaMnO3, charge-density waves in VSe2 originating from 3D nesting of its Fermi surface, Weil semimetals, etc. Buried heterostructures. Our "drosophila" example is the buried LaAlO3/SrTiO3 interface embedding mobile 2D electron gas. Resonant SX-ARPES at the interface Ti3+ ions accentuates its response and exposes the dxy-, dyz- and dxz-derived subbands localized in the interface quantum well. The peak-dip-hump spectral function manifests polaronic nature of the interface charge carriers fundamentally limiting their temperature-dependent mobility [3] and tunable by incorporation of oxygen vacancies. Further examples include multiferroic BaTiO3/La1-xSrxMnO3 interfaces, EuO/Si spin injectors, GaN-based HEMT structures and other buried systems in the heart of electronic and spintronic devices. Buried impurities. Resonant SX-ARPES applied to the paradigm diluted magnetic semiconductor GaMnAs has identified the ferromagnetic Mn impurity band, and established its energy alignment and mechanism of hybridization with the host GaAs bands combining the previous p-d exchange and double-exchange models [4]. Other examples include InFeAs showing the ferromagnetism induced by doped highly mobile electron carriers, magnetic Mn impurities opening the Zeeman gap in the ferroelectric Rashba semiconductor GeTe, etc. [1] V.N.
