| Abstract: | Two-dimensional(2 D) materials are playing more and more important roles in both basic sciences and industrial applications. For 2 D materials, strain could tune the properties and enlarge applications. Since the growth of 2 D materials on substrates is often accompanied by strain, the interaction between 2 D materials and substrates is worthy of careful attention. Here we demonstrate the fabrication of strained monolayer silver arsenide(AgAs) on Ag(111) by molecular beam epitaxy, which shows one-dimensional stripe structures arising from uniaxial strain.The atomic geometric structure and electronic band structure are investigated by low energy electron diffraction,scanning tunneling microscopy, x-ray photoelectron spectroscopy, angle-resolved photoemission spectroscopy and first-principle calculations. Monolayer AgAs synthesized on Ag(111) provides a platform to study the physical properties of strained 2 D materials. |
