Diffusional Phenomena in Microelectronics Processing
For surface diffusion, second ham-ionic microscopy has been utilized to quantify the Arrhenius parameters for diffusion of germanium on silicon at high temperatures. Molecular dynamics simulations provide insight on a picosecond timescale into the complex nature of the mass transfer diffusive …

Modeling contaminant transport and fate and subsequent impacts on ecosystems
… in the sorption process, where best-fit surface diffusivities ranged from 10^{-18} to 10^{-15} cm^2 s^{-1} Intraparticle surface diffusion was incorporated into the Groundwater Modeling System (GMS) to accurately simulate metal contaminant mobility where oxides are present. In the model …

Nanoporous Platinum
… for these structures range from high surface area electrodes for biomedical sensors to use as skeletal structures for fundamental studies (e.g. low temperature heat exchangers or sensitivity of surface diffusivity to chemical environment). In this work we will review our current …

Predicting thermodynamic and transport parameters for metal contaminant sorption to hydrated metal oxides in aquatic systems
… as coatings. These microporous oxides have large surface areas and high affmity for metal ions, and hence they act as both a sink and a source for anthropogenically released metal contaminants. To better understand risks posed by metals in the environment and to develop effective waste management …

Microstructure evolution and interconnect realiability
… that grain-orientation-dependent variations in surface diffusivities constitute a likely cause for the variabilities in lifetimes observed experimentally. The 2D simulation GGSim was also substantially modified to simulate the patterning of interconnect features of general shapes from …
