  "abstract": "The growth of ultrathin tetragonal CuO films by pulsed laser deposition was reported several years ago. In this work, we demonstrate that the same phase can be synthesized using oxygen-plasma-assisted molecular beam epitaxy. We show that it remains stable up to a thickness of 6 nm, significantly exceeding the thickness range previously achieved by PLD.\n\nUsing x-ray diffraction, we resolve its crystal structure and confirm that it consists of a tetragonally distorted rock-salt phase in coherent epitaxy on SrTiO 3 (001), as initially hypothesized. We precisely determine the tetragonal distortion, obtaining a c/a ratio of 1.342(2) for a 3 nm thick film. Using resonant x-ray diffraction, we also demostrate that Co can partially replace Cu without altering the crystal structure. The structural stability of this novel CuO phase upon doping is a key asset for potential future applications in both magnetism and superconductivity",
