2019. Quantum Confinement Effects and Electrostatics of Planar Nano-Scale Symmetric Double-Gate SOI MOSFETs. 2019 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC). :1-3.
The effects of quantum confinement on the charge distribution in planar Double-Gate (DG) SOI (Siliconon-Insulator) MOSFETs were examined, for sub-10 nm SOI film thicknesses (tsi $łeq$ 10 nm), by modeling the potential experienced by the charge carriers as that of an an-harmonic oscillator potential, consistent with the inherent structural symmetry of nanoscale symmetric DGSOI MOSFETs. By solving the 1-D Poisson's equation using this potential, the results obtained were validated through comparisons with TCAD simulations. The present model satisfactorily predicted the electron density and channel charge density for a wide range of SOI channel thicknesses and gate voltages.
