    • Fluctuations in the Lattice Boltzmann Method 

      Kaehler, Goetz August (North Dakota State University, 2012)
      The implementation of fluctuations in the lattice Boltzmann method has made significant progress in the last 10 years. The significance of incorporating noise to all non-conserved degrees of freedom was a significant recent ...

    • Hot Electron Effect in Ultrathin Photovoltaic Junctions 

      Mihaylov, Deyan Ivov (North Dakota State University, 2012)
      The focus of the research work described in the following thesis is increasing the efficiency of photovoltaic devices by reducing hot carrier thermalization losses. In principle this can be achieved by reducing the size ...

    • Electrostatic Interactions at Dielectric Interfaces: From Colloids to Membranes 

      Volpe Bossa, Guilherme (North Dakota State University, 2017)
      In this thesis we have investigated electrostatic interactions at dielectric interfaces using theoretical models based on the non-linear Poisson-Boltzmann theory and its extensions. We have focused on three major topics: ...

    • A Numerical and Analytical Analysis of the Physics of Phase-Separation Fronts 

      Foard, Eric Merlin (North Dakota State University, 2012)
      My dissertation is an investigation into the basic Physics of phase separation fronts. Such phase-separation fronts occur in many practical applications, like the formation of immersion precipitation membranes, Temperature ...

    • The Nature of Single-Wall Carbon Nanotube-Silicon Heterojunction Solar Cells 

      Harris, John Michael (North Dakota State University, 2015)
      Since their inception in 2007, nanotube-silicon heterojunction solar cells have experienced rapid improvement due to the diligent work of several research groups. These devices have quickly reached a point where they might ...

    • Buckling Instabilities of Nanoscale Polymer Films and Colloidal Particle Layers 

      Gurmessa, Bekele Jemama (North Dakota State University, 2015)
      Nanoscale polymer films have numerous potential applications such as protective coatings, flexible electronics, energy harvesting devices, and drug delivery systems. For realization of these potential applications, the ...
