interaction with light, making them ideal for a wide range of applications from piezoelectric devices to multi-layer 2D heterostructures. Janus MXY materials
are 2D materials where a metal atomic layer M is sandwiched between layers X and Y of two different chalcogen, halogen, or pnictogen atoms. The
properties of Janus materials are prone to alter due to interfacial interactions in a heterostructure. Furthermore, the properties of 2D materials can be
dramatically altered by placing them on substrates. Using our ab-initio workflow package, Hetero2D, we compute the energetic stability, electronic
properties, and charge transfer for ~50 Janus materials on 50 elemental, cubic phase, and metallic substrate materials using van der Waals-corrected
density functional theory. Furthermore, we unravel the structure-property correlations at the 2D Janus-substrate heterostructure interface using machine learning
models.
