General Questions and Answers / Energy level of sub-band
« on: December 28, 2013, 14:09 »
I want to calculate the capacitance of device.
For this, i need to find the difference between the energy levels of sub-bands and conductance and valence bands...
but i can not understand how to calculate the energy level of sub-bands?
please help..

Hello
i need a help.
Suppose i made a design containing CNTs or Graphene nanoribbons in ATK 12.2.8. Now i want to make a circuit based on that device like any logic device or memories.
Is it possible to import this device in any other CAD tool? or is there any method in ATK for power and delay analysis?

thanx anders for previous problem..
actually now there is problem in charge stability diagram

please do help....
