Creation of charge carriers by gamma radiation

One important component of the detector resolution is a function of n (this is discussed in Chapter 6) and, other things being equal, one would choose the detector material with a low 8 so as to maximize n. 

Although semiconductor materials provide a ready means by which the electron-hole pairs can be collected. 

In practical terms, this means that the detector material must be available, at reasonable cost, with a high purity and as near perfect as possible crystalline state. Mohihty and trapping will be discussed in more detail later.
