Fig. 1: LVO-KTO interface structural characterization.

(Color online) a Schematic of the LVO-KTO heterostructure showing alternately charged layers in both LVO and KTO leading to formation of 2DEG at the interface (b) RHEED oscillations for 4, 8, and 10 ml LVO-KTO samples and RHEED pattern for 10 ml sample before and after growth of LVO film. c X-ray diffraction pattern of 40 ml sample showing crystalline film growth of LVO on KTO.
