General Questions and Answers / Transmission spectrum for field-effect transistor.

« on: August 29, 2015, 11:00 »

Hi everyone,
I build the FET as attached file below. And then I calculate the transmission spectrum using DFT method with:
- The gate voltage Vg=2V, thickness=1Å
 - Dielectric constant k=3.9εo, thickness=1Å.
When I apply the Source-drain voltage Vd=0, I can obtain the transmission spectrum of FET as showing in attached file. But in the case Vd≠0; I cannot obtain the output file. The work is failed. I don't know why? Please help me!
 
 Thank you!

General Questions and Answers / Single molecular field-effect transistor

Hi everyone!
I try to draw the single molecular (DTB molecule) field-effect transistor but I don't know wheather it is correct with the definition of dielectric layer and gate.
Can you check for me?
Thank you!
