Sa. Komolov et al., PTCDA and NTCDA layers formation on ZnO(0001) and Cu(111) surfaces investigated by total current spectroscopy, PHYS LOW-D, 7-8, 2001, pp. 93-100
The perylene-3,4,9, 10-tetracarboxylic-dianhydride (PTCDA) and naphthalene
is 1,4,5,8-tetracarboxylic is dianhydride (NTCDA) organic macromolecules fi
lms were deposited onto metal Cu(111) and semiconductor ZnO(0001) surfaces.
The total current spectra during films evaporation were measured. The PTCD
A and NTCDA unoccupied electronic structure formation was studied. Two diff
erent formation modes are observed.
