We have calculated current distribution in a porphin molecule connected to two semi-infinite wires using a tight-binding method. We found that loop currents larger than the incident ones, which have been predicted for a few other molecules, also appear in the present case. We also found that the current directions of two paths between electrodes are opposite in certain incident electron energies. These phenomena appear regardless of the electrode positions, though considerable changes by… CONTINUE READING
