(color online) LAO/STO normalized conductance as a function of the reciprocal of temperature, after the dark annealing at 573 K, still shielding the sample from any light (black dots), and illuminating the sample by a UV lamp of 395 nm (pink dots) or by visible light (blue dots). Also the STO substrate conductance (gray dots) is reported for comparison.^{^[44]}
