Bonding of nitrogen-containing organic molecules to the silicon(001) surface: the role of aromaticity

Article Abstract:

The retention of aromaticity is a strong driving force controlling selectivity in bonding of multifunctional molecules to the Si(001) surface. The difference in selectivity between Pyrrole and its derivative 3-pyrroline helps to distinguish between the structural and electronic factors controlling the adsorption process.

Etching and passivation of silicon in alkaline solution: a coupled chemical/electrochemical system

Article Abstract:

A study was conducted to examine the surface chemistry of silicon in alkaline solution. The result shows that the surface chemistry and electrochemistry are determined to a large extend by an activated intermediate of the chemical etching reaction of silicon with water.
