Abstract
We prepare orthorhombic CoSb monolayer films on SrTiO<sub>3</sub>(001) substrate by molecular beam epitaxy and observe symmetric gap around the Fermi level with coherence peaks at ± (6-7) meV by <i>in situ</i> scanning tunneling spectroscopy. <i>Ex situ</i> magnetization measurements of the films protected by Te and Si films consistently reveal a diamagnetic transition at 14 K. These results suggest the occurrence of superconductivity in orthorhombic CoSb monolayers on SrTiO<sub>3</sub>(001).
