Fig. 3

The current, the photon-induced component of the current proportional to photocurrent (dI/dP) and conductance (dI/dV) maps are taken simultaneously over a PTCDA molecule in a constant-height mode as a function of the applied bias voltage in the range from −450−650 mV. Theoretical simulations are provided for comparison. The area of the images is 2 × 2 nm2. The numbers at the top and bottom right corner of each image represent the minimum and maximum data value, respectively. The +max and -min in the color scale bar refer to the maximum positive and minimum negative intensity of the signal.
