include more subbands in the simulation
Closed | Responses: 0
FETToy normally considers the contribution of the lowest subband. how can I include more subbands when doing the simulation? It would be my honor to get replied.
Why is the floating source present in the MOSFET but not in the CNFET?
Hi! I was looking into FETTOY codes for CNFET and MOSFET. I noticed that the floating source is implemented in the MOSFET to ensure charge neutrality but the CNFET code does not have the floating …
substrate of this model
may I know what is the substrate for this model.if I change the substrate of this model,what parameter should I change? example substrate such as SiC, Boron nitrate and diamond like carbon
Expansion of the term FETToy
I would like to know about the gate length of nano scale mosfet
How do I use the floating source potential?

Hi! I was trying to use the MOSFET version of FETTOY and would like to use the floating source potential. I noticed that I need to define the Equilibrium Source Carrier Concentration NSD2D. How do I …
equation of Id
sir, from where can i find equation of Id ,sir in your learning module you have mentioned various equations for double gate but can we apply the same equation to GAA?thanks
Thanks for such a useful tool. How does the entered threshold voltage used in CNTFET calculations, is it just subtracted from gate voltage to obtain effective gate voltage? I cannot see a …
how can i get netlist after simulating silicon nanowire fet device?thank you
FETToy :Can I use this tool to design circuits
Hi, If download the tool, can use it for designing and simulating the circuits for eg;counter,SRAM etc using CNTFET. If not, is it easy to edit and make changes for simulating circuits. …
average velocity vs gate voltage for single and double gate mosfets
The injection velocity vs gate voltage curve for the single and double gate mosfets dips to 0 at gate voltages greater than 0.2 volts. But it shows the usual curve for the nanotubes and nanowires. Is …
Negative voltages for Fettoy
Open | Responses: 2
Hi, i am simulating for negative gate voltages, but i find that i have not been able to do so and i get back an error "mrdivide". does that mean the tool cant simulate for -VG or is there a fix to …
I would like to know the nantube length used in fettoy simulation. Is it 10nm? Does the L affect the drain current?
code posts error message for negative threshold voltages
If I choose a carbon nanotube and a negative threshold voltage the code stops with an error message "mrdivide" or something like this.
