In-situ sheet resistance measurements. The measurements shown here are for the GAO/STO, LAO/STO, LSM/STO, GAO/MgO, GAO/YSZ heterostructures. Measurements on MgO and YSZ substrates remain at the measurement limit. The scale bar in the figure show the conversion of time to thickness for LAO, GAO and LSM.
