Description
Internal Gain in Si timing sensors is needed to overcome the ~100 picosecond lower limit encountered by NA62 GTK and the CMS HGCal projects. We focus on 2 techniques, currently available for achieving internal gain- 1) “reachthrough” in which a high field region is limited to a superficial few micron thick layer and 2) “deep-depleted AD’s where it is deep and the distribution between “drift” and “gain” regions is less distinct.
We have studied deep-depleted avalanche detectors using SILVACO simulations and device characterization and report on the results.
