“…The nature of variation of g m versus V g characteristic curves is attributed to the gate field dependency of hole mobility in Ge-channel devices, which is also consistent with the reported experimental results for Si devices [2,31,33]. Most importantly the feature of our reported characteristics is in contradiction with the theoretical predictions for Si devices in which some constant value of carrier mobility was used in the analysis [21]. The transconductance of Ge devices varies with D it in a complex fashion as observed from Eq.…”
