Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, 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…

Reststrahlen band and optical bandgaps in semiconducting CrN films
Duc V. Dinh, Xiang Lü, Oliver Brandt +8
We present a comprehensive optical characterization of 200-nm-thick CrN(111) films grown simultaneously on AlO(0001) and AlN/AlO(0001) using plasma-assisted molecul…
