- 요약Low temperature plasma sources are frequently used in materials processing applications, and the study of these plasmas is aided by a variety of computational techniques across a broad range of spatial scales. This thesis will explore some of the fundamental limitations on the accuracy of these simulations.Specifically, the numerical thermalization that occurs in particle-in-cell (PIC) simulations will be analyzed in the context of commonly-used momentum-conserving and energy-conserving algorithms (MC-PIC and EC-PIC). It will be demonstrated that the rate of numerical thermalization in multidimensional PIC simulations with grid spacings that resolve the Debye length often exceeds the rate of thermalization due to Coulomb collisions. The numerical processes which modify the electron energy distribution function (EEDF) in multidimensional PIC simulations will be compared with the rates at which real collisional effects modify the EEDF to establish quantitative recommendations for the number of particles per cell necessary for accuracy. I will also use PIC simulations to investigate transport in electron beam-generated plasmas suitable for materials processing applications.Regarding plasma-surface interactions, this thesis will discuss molecular dynamics (MD) and quantum chemistry calculations investigating the adsorption of boron on planar aromatic hydrocarbons using a variety of MD potentials and density functional theory (DFT) methods, establishing how the dependence of key parameters such as adsorption energy and the rate of diffusion along a surface may depend on the careful selection of modeling method.
