Dear Sir,
I have few query about gate terminal,
(1) In the tutorial, I have seen that there is a gap between left electrode cell and the gate terminal (as well as a gap between gate and right electrode cell). Now, for realistic transistor, there should be a little connection between the source (and drain) to the dielectric of the gate terminal. So, in this case, is it taken care of? If so, then what will be the minimum length for this gap? Is the gate length equal to the central region? If the gaps will be there, then how will we define this central region?
(2) In the tutorial, I also have seen that there is a gap between graphene and dielectric region, Is it necessary to keep a gap between these two or can we touch the dielectric with the graphene? If this gap is essential then what should be the minimum gap between the dielectric and graphene? If I want to use other material, then, will we keep same length for these gaps or how will these gaps vary?
Waiting for your earliest reply.
Regards
Ramkrishna
