Hysteretic electrical transport in BaTiO${}_3$/Ba${}_{1-x}$Sr${}_x$TiO${}_3$/Ge heterostructures

J. H. Ngai, D. P. Kumah, C. H. Ahn +1

We present electrical transport measurements of heterostructures comprised of BaTiO${}_3$ and Ba${}_{1-x}$Sr${}_x$TiO${}_3$ epitaxially grown on Ge. The Sr-alloying imparts compressive str…
