High temperature backscatter detector
WebThese consist of a doped semiconductor material (typically silicon) and are placed directly above the sample, as shown in Figure 2. The principle of semiconductor detectors is based on the generation of electron-hole pairs in a semiconductor by the incident BSE electrons. In simpler words: BSE electrons that hit the detectors excite the silicon ...
