The van der Waals (vdWs) forces between monolayers has been a uniquedistinguishing feature of exfoliable materials since the first isolation ofgraphene. However, the vdWs interaction of exfoliable materials with theirsubstrates and how this interface force influences their interaction with theenvironment is yet to be well understood.Here, we experimentally andtheoretically unravel the role of vdWs forces between the recently rediscoveredwide band gap p-type vdW semiconductor violet phosphorus (VP), with varioussubstrates (including, SiO$_2$, mica, Si, Au) and quantify how VP stability inair and its interaction with its surroundings is influenced by the interfaceforce.Using a combination of infrared nanoimaging and theoretical modeling wefind the vdWs force at the interface to be a main factor that influences how VPinteracts with its surroundings.In addition, the hydrophobicity of thesubstrate and the substrate surface roughness modify the vdWs force there byinfluencing VP stability. Our results could guide in the selection ofsubstrates when vdW materials are prepared and more generally highlight the keyrole of interface force effects that could significantly alter physicalproperties of vdWs materials.
