We present electrical transport measurements of heterostructures comprised ofBaTiO$_3$ and Ba$_{1-x}$Sr$_x$TiO$_3$ epitaxially grown on Ge. The Sr-alloyingimparts compressive strain to the BaTiO$_3$, which enables the thermalexpansion mismatch between BaTiO$_3$ and Ge to be overcome to achieve $c$-axisoriented growth. The conduction bands of BaTiO$_3$ and Ba$_{1-x}$Sr$_x$TiO$_3$are nearly aligned with the conduction band of Ge, which facilitates electrontransport. Electrical transport measurements through the dielectric stackexhibit rectifying behavior and hysteresis, where the latter is consistent withferroelectric switching.
