The model calculates the subband energies and the semiconductor charges by considering the wave function penetration into the gate insulator, effective mass discontinuity at the semiconductor-oxide interface, 2-D confinement in the NW, and Fermi-Dirac statistics. The semiconductor charge expression proposed in this paper is completely explicit in terms of applied gate voltage, therefore, making it highly suitable for large circuit simulations. The model is also compared with the results from self-consistent Schrödinger-Poisson solver for different NW sizes and materials and found to be accurate over a wide range of gate voltages.falseCircuit simulation | density of states (DOS) | III-V | MOS transistor | nanowire (NW) | quantum capacitanceArticle4889-4896December 2017138103305arJournal13
