We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

  Is there any example file (charge simulation) available for silicon-based SPAD?

  As long as the material properties are proper, I believe you can simulate the PAD device. I would like to encourage you to do the simulation with CHARGE. Please refer to the online examples and let me know if you have any questions from the simulation.

  Do you have any example file of Si-based SPAD where the dark current and I-V curves have already been calculated? It would be easy for me to start with.

  As I mentioned, there is no difference whatever the semiconductor material you use for simulation of such device. Just follow the examples online to set up your simulation and contact us should you have questions.
