How to Make Multiple Channel For a GAA CNT FET & increase Source & drain Height?

[techenthusiast]

Dear All,


Good morning, Just to ask : How to Make Multiple Channel(At least 2)  For a GAA  CNT FET Using Quantum Atk in NEGF formation?.  With Same chirality say (10,0).Thank You.
How to increase Source & drain Height with the same chirality of CNT ?

Thank you.

Also, Is there any technical scientific provision for molecular  adsorption effect mechanism(Maybe Vander Wal force between target molecules & the CNT based scattering region/Channel) ? for those channels(each).   Kindly Let me know,
