Oxidation Mechanism of Hydrogen-Terminated Silicon Surface.

Rapid Surface Functionalization of Hydrogen-Terminated Silicon by Alkyl Silanols

Surface functionalization of inorganic semiconductor substrates, particularly silicon, has focused attention toward many technologically important applications, involving photovoltaic energy, biosensing and catalysis. For such modification processes, oxide-free (H-terminated) silicon surfaces are highly required, and different chemical approaches have been described in the past decades. However...

Chlorination of hydrogen-terminated silicon „111... surfaces

Infrared absorption spectroscopy was used to investigate the chlorination of hydrogen-terminated Si 111 surfaces by three different methods: a exposure to a saturated solution of phosphorus pentachloride PCl5 in chlorobenzene; b exposure to chlorine gas, Cl2 g , and c exposure to Cl2 g under UV illumination. X-ray photoelectron spectroscopy and first principles model clusters calculations were ...

Indications of chemical bond contrast in AFM images of a hydrogen-terminated silicon surface

The origin of bond-resolved atomic force microscope images remains controversial. Moreover, most work to date has involved planar, conjugated hydrocarbon molecules on a metal substrate thereby limiting knowledge of the generality of findings made about the imaging mechanism. Here we report the study of a very different sample; a hydrogen-terminated silicon surface. A procedure to obtain a passi...

Step structure and surface morphology of hydrogen-terminated silicon: (0 0 1) to (1 1 4)

We have determined the equilibrium step structures and surface morphology for the whole range of monohydrideterminated (0 0 1)-terrace-plus-step silicon surfaces using scanning tunneling microscopy. The transformation in the equilibrium Si surface morphology caused by H-termination can be categorized into three different regimes delineated by the types of steps present on the clean surfaces. On...
