Electro-thermal models have to be used to optimize the performance of the devices themselves but also the multipliers. We have developed a circuit simulator that couples the embedding circuit with a numerical physics-based electro-thermal model for Schottky diodes. This model takes into account both the electrical limiting transport mechanisms and also self-heating. The thermal characteristics are taken into account by adding the heat conduction equation to an existing physics-based electrical model based on the drift-diffusion theory. This additional equation applies conservation of energy to the composite system consisting of electrons, holes, and phonons.
