Two‐dimensional (2D) van der Waals (vdW) materials have garnered considerable attention for their unique properties and potentials in a wide range of fields, which include nano‐electronics/optoelectronics, solar energy, and catalysis. Meanwhile, challenges in the approaches toward achieving high‐performance devices still inspire the search for new 2D vdW materials with precious properties. In this study, via molecular beam epitaxy, for the first time, the vdW SnI2 monolayer is successfully fabricated with a new structure. Scanning tunneling microscopy/spectroscopy characterization, as corroborated by the density functional theory calculation, indicates that this SnI2 monolayer exhibits a band gap of ≈2.9 eV in the visible purple range, and an indirect‐ to direct‐band gap transition occurs in the SnI2 bilayer. This study provides a new semiconducting 2D material that is promising as a building block in future electronics/optoelectronics. The great application potentials and challenges in high‐performance devices inspire the search for new two‐dimensional (2D) van der Waals (vdW) materials. Via molecular beam epitaxy, the vdW SnI2 monolayer is successfully fabricated with a new structure. This SnI2 monolayer is a 2D semiconductor with thickness‐dependent properties, which is promising as a building block in future electronics/optoelectronics.
