dc.description.abstract | In this work, a tunneling field-effect transistor (TFET) in the structure that can maximize the electrostatic effects in determining its electrical performances is optimally designed and characterized. The featured device structure includes gate-all-around (GAA) channel and dual gates (DuGs) identified as control gate (CG) and adjust gate (AG), respectively. Not along with the design tasks, more fundamental studies on the effects of respective gates on device performances are sought. It has been found that the relatively different vicinities of the DuGs to source and drain junctions have differentiable dominances in controlling the primary direct-current (DC) parameters of the TFET including threshold voltage (Vth), on-state current (Ion), subthreshold swing (S), and on/off current ratio (Ion/Ioff). For the systematic study, four different cases have been presumably schemed giving the degree of freedom in gate workfunctions and inter-gate connectivity. It has been found that the CG at the source side more effectively modulates Vth, Ioff, and S, while the AG at the drain side shows the higher controllability over Ion and Ion/Ioff of the TFET. An optimally designed GAA DuG demonstrated Ion/Ioff > 1011 along with a small S of 14.6 mV/dec, which supports the strong potential of the GAA DuG TFET in the low-power applications. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature. | - |
