Synthesis of epitaxial TaO $_{2}$ thin films on Al $_{2}$ O $_{3}$ by suboxide molecular-beam epitaxy and thermal laser epitaxy

Yorick A. BirkhÃ¶lzer, Anna S. Park, Noah Schnitzer +28

Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…

Atomic multiplet and charge-transfer screening effects in 1 $s$ and 2 $p$ core-level X-ray photoelectron spectra of early 3 $d$ transition-metal oxides

Tatsuya Yamaguchi, Keisuke Higashi, Anna Regoutz +5

We present a comparative analysis of 1 $s$ and 2 $p$ core-level hard X-ray photoelectron spectroscopy (HAXPES) spectra in metallic VO $_{2}$ and CrO $_{2}$ . Even though the V 1 $s$ and 2 $p$ …
