Description
Proton model (effective 2-defect model based on the EVL model) used in Synopsys Sentaurus package, has proven to produce matching simulation results with measurements. However, at high fluence (> 1e15 cm-2) and thus high oxide charge, the model does not produce radiation enhanced isolation to the strips, observed in a real p-type detector. Also simulated Cint and CCE loss in the center of the pitch reflect this shortcoming. Novel non-uniform 3-level defect model solves these problems without affecting the experimentally matching simulation results of proton model.
Edge-TCT provides a method for the measurement of the drift velocity of the charge carriers as a function of depth. This could make it possible to extract electric field distribution in the detector bulk. Comparison of non-irradiated/irradiated device edge-TCT simulations with measurements will be presented.
