Electronic structure and signature of Tomonaga–Luttinger liquid state in epitaxial CoSb1−x nanoribbons

npj Quantum Materials, 2021
Recently, monolayer CoSb/SrTiO3 has been proposed as a candidate harboring interfacial superconductivity in analogy with monolayer FeSe/SrTiO3. Experimentally, while the CoSb-based compounds manifesting as nanowires and thin films have been realized on ...

X-ray fluorescence holography under high-pressure conditions

Journal of Synchrotron Radiation
This study reports the first application of X-ray fluorescence holography (XFH) under high-pressure conditions. We integrated XFH with a diamond anvil cell to investigate the local structure around Sr atoms in single-crystal SrTiO3 under high pressure ...

A comparative study of superconductivity at LaAlO3/SrTiO3 and BaTiO3/LaAlO3/SrTiO3 heterointerfaces

AIP Advances, 2023
Lead-free BaTiO3 (BTO) film was fabricated by pulsed laser deposition on LaAlO3/SrTiO3 (LAO/STO) heterostructure in oxygen pressure of 2 × 10−3 Pa, which is experimentally required for ensuring the two-dimensional electron gas at LAO/STO heterointerface.
