The dependences of the electron mobility μeff in the inversion layers of fully depleted double–gate silicon-on-insulator (SOI) metal–oxide–semiconductor (MOS) transistors on the density Ne of induced charge carriers and temperature T are investigated at different states of the SOI film (inversion–accumulation) from the side of one of the gates. It is shown that at a high density of induced charge carriers of Ne > 6 × 1012 cm–2 the μeff(T) dependences allow the components of mobility μeff that are related to scattering at surface phonons and from the film/insulator surface roughness to be distinguished. The μeff(Ne) dependences can be approximated by the power functions μeff(Ne) ∝ Ne−n. The exponents n in the dependences and the dominant mechanisms of scattering of electrons induced near the interface between the SOI film and buried oxide are determined for different Ne ranges and film states from the surface side.
