Scanning tunneling microscopy and scanning tunneling spectroscopy studies of planar and nonplanar naphthalocyanine on graphite (0001). Part 2: Tip-sample distance-dependent I-V spectroscopy
Article Abstract:
The distance-dependent current-voltage (I-V) spectroscopy of the base-free naphthalo-cyanine (planar) and tin-naphthalocyanine (nonplanar) on a comparatively weak interacting substrate as highly oriented pyrolytic graphite (HOPG) is studied. The current-voltage curves show an unsymmetrical diode-like nature especially at large tip-sample distance in both cases.

Scanning tunneling microscopy and scanning tunneling spectroscopy studies of planar and nonplanar naphthalocyanines on graphite (0001). Part 1: Effect of nonplanarity on the adlayer structure and voltage-induced flipping of nonplanar tin-naphthalocyanine
Article Abstract:
The adsorption of base-free napthalocyanine (planar) and tin-naphtalocyanine (nonplanar) on a graphite basal plane is compared, The planar molecules form large areas of defect-free ordered monolayer at high molecular packing density while the nonplanar molecules show different phases of adsorption with lower molecular packing density.
