Abstract : The Hall and effective mobility characteristics of n-type junctionless transistors (JLTs) at low temperature (T=100K) are reported here for the first time. To this end, the effective mobility values (μ Eff ) were extracted from the charge based analytical model of JLT with account for flat-band (VFB) position and split capacitance-to-voltage (CV), respectively. Besides, in order to directly determine the surface carrier density (N s ) and corresponding Hall mobility (μ Hall ) Hall Effect measurements were carried out and compared to μ Eff .
Keywords : Split CV measurement Flat-band voltage Mobility Junctionless transistor Hall Effect measurement
