Interfacial chemistry of pentacene on clean and chemically modified silicon (001) surfaces

Article Abstract:

The interactions between pentacene and the Si(001)-(2 x 1) surface is investigated using Fourier transform infrared spectroscopy (FTIR), ultraviolet photoelectron spectroscopy (UPS), and X-ray photoelectron spectroscopy (XPS). The interaction between pentacene and the Si(001) surface involves an initial layer of molecules whose electronic structure and crystallinity differ consequently from those of thicker multilayer pentacene films.

Formation of an atomically abrupt interface between a polycyclic aromatic molecule and the silicon (001) surface via direct Si-C linkage

Article Abstract:

The reaction of acenaphthylene with the Si(001) surface is investigated as a model system for understanding the way complex pi-systems interact with a pi-bonded semiconductor surface. The reaction between acenaphthylene and Si(001) represents a potential method for coupling extended pi-electron systems with group IV semiconductor surfaces.

Sulfur atoms as tethers for selective attachment of aromatic molecules to silicon(001) surfaces

Article Abstract:

Benzenethiol [C(sub 6)H(sub 5)SH] and diphenyl disulfide bond [C(sub 6)H(sub 5)S-SC(sub 6)H(sub5) were used as model systems to compare the interaction of chemically similar pie-conjugated molecules with the Si(001)-2*1 surface. The majority of aromatic rings are left intact and tethered to the surface through a group VI atom.
