Enhanced superconductivity in TiO epitaxial thin films

Condensed matter physics: enhancing superconductivity in TiO The cubic titanium monoxide undergoes a superconducting transition at 2 K in its bulk form. However, access to the superconductivity mechanism is blocked by the lack of TiO single crystals or epitaxial films. Now, Prof. Xiaoguang Li and hi...
