The spatial evolution of the background conductance in the tunneling spectra was investigated with low-temperature scanning tunneling spectroscopy on a slightly overdoped Bi 2 Sr 1.74 La 0.26 CuO 6+δ single crystal at 4.2 K. The asymmetry in the background conductance between positive and negative biases strongly correlates with the local energy gap, which shows the inhomogeneous spatial variation: the tunneling spectra become more asymmetric in the regions where the spectra exhibit larger gap value.
