Applications of p-i-n Structures in EM-related Devices

Figure 3807 shows the structure of EDS detector. The active Si can be an intrinsic silicon crystal in thickness of about 3 mm. The collector of e-h pairs is a reversed p-i-n structure. The Si dead layers are p-/n-type silicon crystal in thickness of about 100 nm. The existing dead layers also indicate that the generated charges cannot be completely detected.
