Model Equations

We present analytical model equations for threshold voltage (Vth) and saturation voltage (Vds,sat) characterizing CNT-FETs. These model equations have been obtained from the charge and potential distributions between the gate and substrate in a CNT-FET. It is shown that both Vth and Vds,sat are strongly dependent on chiral vectors of CNTs. The results show close agreement between theoretical and graphical modeling techniques. It is also shown that the calculated Vth of a CNT-FET with chiral vector (3, 1) is in close agreement with the corresponding published work.
