(a) The R ( T ) curve of superconducting Si/(10-UC)FeTe/(1-UC)FeSe/STO heterostructure, showing and . The inset is a schematic structure for standard four-electrode measurement. (b) Temperature dependence of magnetization for 1-UC FeSe film on intrinsic STO measured at a parallel field of 1000 Oe. Typical magnetic hysteresis loop is shown in the inset. Insulating-like properties of the STO substrate, 10-UC FeTe/STO, and Si/10-UC FeTe/STO heterostructures are shown in panels (c) and (d), respectively.^{[ 23 ]}
