  2. Where, why, and how you used Dyson equation

    Open | Responses: 1

    It's mentioned that Dyson equation is used. Would you please let me know in which part you used Dyson equation. Which part of Hamiltonian considered as perturbation and why? I couldn't find it in the …

  3. Why the effect of temperature is different at on and off-state current?

    Open | Responses: 1

    For V(drain)=0.1V or 0.4V and V(gate)=0V, by increasing the temperature (300ºk, 400ºk, 500ºk) the current (off-state current) increases. Such behavior can be seen for V(drain)=0.4V and V(gate)=1V …

  4. why the saturation current increases with decrease in diameter of the CNT

    Closed | Responses: 3

    I had done the simulation using your tool “CNTFET Lab” available at nanohub. I have done the simulations for different diameter of the CNT (by changing the chirality) used in the channel. The …

  5. is there a problem with the simulator?

    Closed | Responses: 1

    hi, I tried to get some I-V curves but I couldnt (even with default settings)I just get values of drain source or gate voltage and there is not any curve, just the values..

  6. what is the threshold voltage

    Closed | Responses: 3

    for simulation of CNTFET what is the exact value of the threshold voltage? how does this depends on the device parameters.

  8. why I~vds curve shows higher saturation current for longer channel length?

    Open | Responses: 1

    I was simulating for CNTFETs with different channel length.I had taken a (10,0) CNT.I tried to plot I~vds curve for channel lengths 10nm,15nm and 30nm.saturation current for 10nm is coming higher …
