How to calculate Quantum capacitance of a graphene sheet using ATK?
Can someone help me with this, plzz.

Thank you very much for your time.

There is no standard feature in the ATK to do this kind of calculation. But I guess you may first calculate the density of states of a graphene sheet in the ATK to then get this capacitance in a post-processing manner.

Yes, you are right.   
For example, the following papers estimated the quantum  capacitance from density of states:
J. Phys. Chem. C 2015, 119, 6464−6470
J. Phys. Chem. C 2014, 118, 4 − 15

Thank you very much Dr. petr and Dr. Zh for the papers.
I will go through these papers and get back if there is any issue.

thank you.
