May 21, 2003 · On the other hand, semiconductor devices like silicon (Si) or germanium (Ge) lead to excellent energy resolution. However, Si offers a low stopping power for high-energy photons, limiting its use to low energy. On the other hand, the small band-gap of germanium requires operations of the detectors at cryogenic temperatures.

The effect of piezoresistance in germanium and silicon was discovered by C.S. Smith in 1954 [1].It was found that the resistance of a germanium or silicon filament changed when the material was stressed. The effect of piezoresistance is similar to the strain gauge effect in a metal material, but the differences between them are quite fundamental:
