Abstract

The angle-resolved ultraviolet photoelectron spectra of ultrathin films of metal-free phthalocyanine (H₂Pc) and copper phthalocyanine (CuPc) on MoS₂ single crystal surfaces were measured using synchrotron radiation. The take-off and azimuthal angle dependencies of the photoelectron intensity were analyzed using independent-atomic-center approximation combined with molecular orbital calculation. Further, the low energy electron diffraction was observed for the same ultrathin films. The results indicate that H₂Pc and CuPc molecules form a square lattice with respect to the three equivalent crystal axes of the MoS₂ surface, and at the lattice point lie flat on the substrate with a molecular azimuthal rotation of about 7°.
