Correlating polar distortions and interfacial charge at the polar/non-polar LaCrO3/SrTiO3 (001) interface [PDF]

AIP Advances, 2020
The relationship between the sheet carrier concentration, ns, of LaCrO3(LCO)/SrTiO3(STO) heterostructures and their structural properties has been investigated. Under low oxygen partial pressure, the STO substrate is reduced during growth as evidenced by a high ns of 1016 cm−2.
