WebHere, is the substrate impurity concentration, is the bulk Fermi energy, and is the intrinsic carrier concentration of Si (cm at 300 K). Figure 5.2 shows that the mobility characteristics of MOSFET inversion layers can be split into three distinctive regions. At low inversion charge densities (low vertical fields), mobility is limited by scattering with doping atoms … WebThe effective mobility in a MOSFET is intimately related to the average mobility of the carriers forming the inversion channel. From an experimental point of view, the effective mobility can be obtained by normalizing the drain current Id I d in linear regime by the inversion charge Qi Q i as μeff = L W. Id Q.V d. (1) (1) μ e f f = L W.
