PTCDI-C8 Adsorption on Si(100)

Adsorption of N, N'-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) on the Si(100) surface has been examined using X-ray photoelectron spectroscopy and scanning tunneling microscopy. X-ray photoelectron spectroscopy results show that the bonds are formed between the carbonyl groups of the molecules and the substrate. Scanning tunneling microscopy results show that the first and further layers are disordered.
