Reconfigurable electrostatically doped 2.5-gate planar field-effect transistors for dopant-free CMOS

摘要

In this paper, we demonstrate by extending TCAD simulations based on experimental data of fabricated electrostatically doped, reconfigurable planar double-gate field-effect transistors, the improved characteristics of a triple gate device design. The technological cornerstones for this general-purpose FET comprise mid-gap Schottky S/D junctions on a silicon-on-insulator substrate. The transistor type, i.e. n-type or p-type, is interchangeable during operation by applying a control-gate voltage which significantly increases the flexibility and versatility in the design of integrated circuits.
