Abstract: Deterministic control of the layering configuration of two-dimensional quantum materials plays a central role in studying their emergent electronic properties. Here we demonstrate in situ control over competing stacking configurations in thin film crystals of the rare-earth diantimonides by synthesizing in proximity to competing structural orders. A crossover between the epitaxially stabilized monoclinic structure and the orthorhombic structure commonly observed in bulk crystals is navigated through three axes─the relative cation/anion ratio, growth temperature, and choice of lanthanide ion─culminating with a comparative magnetotransport study of single-yet-distinct phase CeSb 2 films. These results set the stage for an expanded search for hidden stacking configurations in layered compounds which have evaded detection.
