Orbital mediated tunneling in vanadyl phthalocyanine observed in both tunnel diode and STM environments

Article Abstract:

It has been possible to identify the orbital mediated tunneling spectroscopy (OMTS) of a compound, vanadyl phthalocyanine, in both the tunnel diode and STM environment. OMTS can be used in both environments to assess electron affinities for adlayers on metal surface.

Physical properties and metal ion specific scanning tunneling microscopy images of metal(II) tetraphenylporphyrins deposited from vapor onto gold (III)

Article Abstract:

High resolution scanning tunneling microscopy (STM) data are presented that clearly shows the individual metallotetraphenylporphyrins (MTPP) molecules and allows easy differentiation between NiTPP and CoTPP, even when mixed monolayer structures are studied. Infrared and X-ray photoelectron spectroscopy both indicate that thin films of CoTPP, NiTPP and CuTPP may be vapor deposited onto Au without chemically modifying the deposited molecule.
