Every software package contains a full set of examples suitable for that version and are installed with the software. If you see examples here that are not in your installation you should consider updating to a later version of the software. These examples can be used by beginners and advanced users for product evaluation, teaching purposes, and self-training.

This example demonstrates crosstalk extraction in a InSb detector.
Crosstalk is one of the main parameters that critically affect the resolution of detector arrays. Electrical crosstalk is attributed to carriers that are photogenerated under one detector, diffusing and being collected by another detector in the array. As the photodiode size and the pitch (distance between photodiodes) of the detector array get smaller, there is a greater probability of crosstalk influencing system performance since the probability of a generated carrier being collected by a neighbouring junction increases. Victory Device is used to study the crosstalk of a 5 x 5 InSb detector array in the three dimensional domain.
The structure consists of InSb photodiodes fabricated on top of the InSb buffer layer. The p+ regions were doped with acceptor concentration of 1 x 1019 cm-3 and the buffer layer was doped with donor concentration of 1 x 1015 cm-3. The contacts on these photodiodes are ohmic and they are named as anode 1, anode 2, … anode 25 in the simulation. The cathode is formed on top of the buffer layer surrounding the photodiodes.
In this simulation, a multi-spectral source will be used and the source will be a black-body radiator operating at a temperature of 2000 Kelvin. The power.file parameter in the BEAM statement will be used for that purpose.
