Abstract
- In order to reduce dead zone of Closed Shell-Electrode Silicon Detector (CSESD), this paper introduces an optimal scheme of 3D shell electrode type detector– a novel type of Honeycomb Shell Electrode Detector– HSED (Chinese patent #zl 201710 676008.3). In this paper, we first study dead zone of the new structure and find dead zone of non-elongated HSED cell is smaller than that of CSESD. An array arrangement method of CSESD is also proposed, which makes virtually no dead zone in the array comprised by elongated detector cells. Detector electrical simulations with SILVACO TCAD, including I-V and C-V characteristic, will be given. Then, the structure with different nesting depth and dbot is simulated with SILVACO TCAD. It has been found that the closer nesting position is to the surface, the smaller dead zone is, and the deeper the nesting is, the larger the dead zone is. However, through the simulation of the weighting field, it is found that the deeper the nesting depth, the smaller the influence of the weighting field by neighboring cell.
