Abstract
The temperature-dependent performance, including drain current (Id) and gate capacitance (Cgg) of multi-gate junctionless (JL) bulk transistor for temperature (T) ranging from 150 K to 500 K, was investigated using 3D thermodynamic quantum-corrected device simulation. The combination effect of impurity scattering and phonon scattering is observed owing to the different temperature-dependent of mobility at low and high temperature. Since the Cgg of the JL device consists of a series combination of oxide capacitance (Cox) and semiconductor channel capacitance (CS) due to bulk conduction of the current, the Cgg at on-state (Vg = 1 V) shows much sensitive to the temperature than a conventional inversion-mode transistor.
