Abstract
Estimation of total channel charge Q Tot of carbon nanotube field effect transistor from the selfconsistently computed charge density Q Top at the top of conduction band subband minima is found to be inaccurate A regional approach based on extended ballistic transport theory is proposed to model Q Tot and its partitioning into source and drain components The models for charges and subsequently derived capacitances are validated with the numerically simulated data obtained using semiclassical technique The model agreement with numerical data shows the superiority of our regional approach compared to ones obtained from only the information of Q Top
