Curves of current of LCMO/STON heterojunction versus 1/ T (a) and T (b), measured under various biases, the inset in panel (a) shows the line relation between activation energy and bias. The curves of current of LCMO/LAO/STON heterojunction versus T (c) and 1/ T (d). The inset of panel (c) shows a linear relation between the parameter T ₀ and bias.
