The electronic states between Si(111) and a Si(111)-(7×7) surface was observed using the noncontact atomic force spectroscopy (nc-AFS). The nc-AFS provides new analytical prospects for force interaction between solid bodies, including metals. The spectra show prominent peaks and a broad peak, which are attributed to quantum mechanical resonance as the energy levels of sample surface states are tuned to those of the tip states by shifting the Fermi level through changing bias voltage. The energy level tuning by shifting the Fermi level has great potential for atom recognition and manipulation.
