Complex oxides provide a versatile playground for many phenomena and possible
applications, for instance, high-temperature superconductivity, magnetism, ferroelectricity …

We use resonant inelastic x-ray scattering (RIXS) at the OK-and Cu K-edges to investigate
the do** dependence and temperature dependence of low-energy plasmon excitations in …

Compositional tuning of layered perovskite oxides provides a means of systematically
studying how local distortions affect fundamental aspects of electrochemical reaction …

There is a hot debate on the anomalous behavior of superfluid density ρ s in overdoped La 2-
x Sr x CuO 4 films in recent years. The linear drop of ρ s at low temperatures implies the …

We report on the development of a high-resolution and highly efficient beamline for soft X-
ray resonant inelastic X-ray scattering (RIXS) located at the Taiwan Photon Source. This …

We have used atomic layer-by-layer oxide molecular beam epitaxy to grow epitaxial thin
films of L a 2− x C ax C u O 4 with x up to 0.5, greatly exceeding the solubility limit of Ca in …

Recent experimental papers on hole-doped overdoped cuprates have argued that a series
of observations showing unexpected behavior in the superconducting state imply the …

We demonstrate how ordered arrangements of oxygen vacancies can be engineered during
the growth of superconducting La 2 CuO 4 films by oxide molecular-beam epitaxy. These …

The synthesis of stoichiometric Sr 2 RuO 4 thin films has been a challenge because of the
high volatility of ruthenium oxide precursors, which gives rise to ruthenium vacancies in the …

Microscopic studies on thin film superconductors play an important role for probing non-
equilibrium phase transitions and revealing dynamics at the nanoscale. However, magnetic …
