Hole mobility in fully-depleted GeOI pMOSFETs is determined and analyzed using for the first time the geometric magnetoresistance technique. The temperature dependent measurements clarify the scattering mechanisms. A significant difference between effective mobility and magnetoresistance mobility is found. Unlike the SOI nMOSFET, this ratio (rMR ≃ 1.8) is rather independent on the temperature and inversion charge pointing out special scattering mechanisms.
