Thermionic emission, secondary electron emission, the development of plasma sheaths, and ion-material interactions such as reflection, sputtering, and chemical or morphological changes brought about by implantation are but a few of the microscopic interactions that can have a macroscopic effect on plasma. Due to their complexity, plasma-material interactions are often analyzed using reduced models, such as empirical formulas for the sputtering yield or simplifying assumptions such as the logical sheath; however, the use of reduced models obscures much of the complexity of the interaction. To accurately model the plasma-material interface, near-first-principles models must be developed. Most promising among these in terms of feasible computation are the particle-in-cell kinetic plasma model and the binary collision approximation ion-material interactions model. By directly coupling these two models, a fully kinetic, widely applicable model of plasma-material interactions can be developed without resorting to reduced models or overly simplifying assumptions. In order to fill this role, I have developed RustBCA, a from-scratch, high-performance, modern BCA code, and with it, bindings for coupling that have allowed its integration into an advanced particle-in-cell code. Additionally, novel RustBCA features such as arbitrary attractive-repulsive potentials and 3D morphology will allow higher fidelity modeling of the plasma-material interface than has been available previously. In this work, the design and development of RustBCA, its novel features, and the construction of a coupled particle-in-cell and binary collision approximation code will be covered.
