Abstract : By definition, the Fano factor (F) is an intrinsic material constant which reflects the ultimate detector resolution. The paper points out the difficulties associated with Fano factor measurements; attempts to clarify the mechanisms of some apparently anomalous behavior frequently observed in solid state detectors; presents some new experimental results for F in silicon and germanium; and derives a phenomological model for the average energy expended to produce an electron-hole pair (epsilon), which is then used to predict semitheoretical values of F.
