    • -1 at 77 K is estimated for physisorption, although the actual energy barrier for adsorbed molecule to diffuse to the nearest neighbor sites must be much smaller than 40 kJ/mol. Next we should consider the path length for molecules to reach the particular site with distinct enhancement from ordinary sites with modest enhancement. According to our calculation, the maximum field is concentrated only at the junction within ca. 5 nm at most (see Figures 12A and 6C,D). If we accumulate the average effective length for ca. 0.3 s (blinking frequency) based on the above equation, the distance 5 nm is a possible value for molecules to diffuse. Thus, the blinking can be suppressed or the frequency is diminished at low temperature by losing the thermal energy.
