Surface-state engineering for interconnects on H-passivated Si(100).
Surface-state engineering strategies for atomic-size interconnects on H-passivated Si(100) surfaces are explored. The well-known simple interconnect formed by removing H-atoms from one of the Si atoms per dimer of a dimer row along the Si(100) surface is poorly conducting. This is because one-dimensional-like instabilities open electronic gaps. Here, we explore two strategies to reduce the inst...
متن کاملHydrogen Induced Si Surface Segregation on Ge-Covered Si(001)
Using Fourier transform infrared-attenuated total reflectance spectroscopy in conjunction with hydrogen adsorption to probe surface layer composition, we observe a reversible place exchange between Ge and Si on Ge-covered Si(001) when the surface is dosed with atomic H at elevated temperatures. First-principles calculations confirm a thermodynamic driving force for this place exchange. To expla...
متن کاملFirst principles studies of an Si tip on an Si(100)2 × 1 reconstructed surface.
We present a systematic study of the interaction between a silicon tip and a reconstructed Si(100)2 × 1 surface by means of total energy calculations using density functional theory. We perform geometry optimization to obtain the reconstructed Si surface using the local density approximation and the generalized gradient approximation methods and compare our results with those obtained experimen...
متن کاملPhosphine dissociation on the Si(001) surface.
Density functional calculations are performed to identify features observed in STM experiments after phosphine (PH3) dosing of the Si(001) surface. On the basis of a comprehensive survey of possible structures, energetics, and simulated STM images, three prominent STM features are assigned to structures containing surface bound PH2, PH, and P, respectively. Collectively, the assigned features o...
متن کاملATR-SEIRAs characterization of surface redox processes in G. sulfurreducens.
In this work we report on the occurrence of at least two different redox pairs on the cell surface of the electrogenic bacteria Geobacter sulfurreducens adsorbed on gold that are expressed in response to the polarization potential. As previously reported on graphite (Environ. Sci. Technol. 42 (2008) 2445) a typical low potential redox pair is found centered at around -0.06 V when cells are pola...
