Stacking-Selective Epitaxy of Rare-Earth Diantimonides.

Deterministic control of the layering configuration of two-dimensional quantum materials plays a central role in studying their emergent electronic properties. Here we demonstrate 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 films.

Monoclinic LaSb Superconducting Thin Films.

Rare-earth diantimondes exhibit coupling between structural and electronic orders, which are tunable under pressure and temperature. Here we present the discovery of a new polymorph of LaSb stabilized in thin films synthesized using molecular beam epitaxy. Using diffraction, electron microscopy, and first-principles calculations we identify a YbSb-type monoclinic lattice as a yet-uncharacterized stacking configuration.

2-({[(2)-1-Hy-droxy-1,1,3-tri-phenyl-propan-2-yl]imino}-meth-yl)-4,6-bis-(4-methyl-phen-yl)phenol.

The title compound, CHNO, crystallizes in the ortho-rhom-bic space group 222 with one mol-ecule in the asymmetric unit. An intra-molecular hydrogen bond orients the phenol hydroxyl group toward the imine nitro-gen. The aliphatic alcohol is engaged in a weak intra-molecular hydrogen bond with the imine nitro-gen.
