Abstract: A novel super-resolution photon scanning tunneling microscope (PSTM) using diode lasers and optical fibers was demonstrated to measure the samples with submicron structure in a noncontact and nondestructive manner. A reproducible method for fabrication of the fiber probe with the tip curvature radius of 80 nm is reported. The step with the height of 9 nm, optical disk with submicron-sized pits similar to moth-eye structure, and latex particles with 80 nm in diameter have been observed. To the best of our knowledge, this is the smallest particle size resolved by the PSTM.
