Hysteretic electrical transport in BaTiO/BaSrTiO/Ge heterostructures
J. H. Ngai, D. P. Kumah, C. H. Ahn +1
We present electrical transport measurements of heterostructures comprised of BaTiO and BaSrTiO epitaxially grown on Ge. The Sr-alloying imparts compressive str…

Modifying the Electronic Orbitals of Nickelate Heterostructures Via Structural Distortions
Hanghui Chen, Divine P. Kumah, Ankit S. Disa +3
We describe a general materials design approach that produces large orbital energy splittings (orbital polarization) in nickelate heterostructures, creating a two-dimensional singl…
