The paper introduces an analytical model for gate all around (GAA) or Surrounding Gate Metal Oxide Semiconductor Field Effect Transistor (SG-MOSFET) inclusive of quantum mechanical effects. The classical oxide capacitance is replaced by the capacitance incorporating quantum effects by including the centroid parameter. The quantum variant of inversion charge distribution function, inversion layer capacitance, drain current, and transconductance expressions are modeled by employing this model. The established analytical model results agree with the simulated results, verifying these models' validity and providing theoretical supports for designing and applying these novel devices.

An organic ferroelectric capacitor, using polyvinylidene difluoride (PVDF) as the dielectric, was fabricated. By connecting the PVDF capacitor in series to the gate of a commercially purchased metal-oxide–semiconductor field-effect transistor (MOSFET), drain current (ID)–drain voltage (VD) characteristics and drain current (ID)–gate voltage (VG) characteristics were measured. In addition, the subthreshold slopes of the MOSFET were determined from the ID–VG curves. It was found that the subthreshold slope could be effectively reduced by 23% of its original value when the PVDF capacitor was added to the gate of the MOSFET.
