Suitable semiconductors for gamma-ray detectors

To summarize the previous sections we can say that the ideal semiconductor detector material will  

Taking all these items into account leaves only a few possible candidates, selected data for which are shown in Table 3.1. The most obvious candidate is silicon that.
