Dear All,

Can we use ATK to calculate impact ionization scattering rate of carbon nanotubes? Thank you very much.

Attached please find related equations in reference: Perebeinos, V. and P. Avouris, Impact excitation by hot carriers in carbon nanotubes. Physical Review B, 2006. 74(12): p. 121410.

General Questions and Answers / Print results of deformation potential

« on: October 6, 2015, 14:46 »

Dear All,

I calculated the deformation potential in graphene following the example at http://www.quantumwise.com/documents/manuals/ATK-2015.beta/ReferenceManual/XHTML/ref.deformationpotential.html,   and used nlprint(stream) to print a string containing an ASCII table with deformation potential data of deformation_potential_2 in the example code.

Attached is the results I got. The scaled (|g|) and unscaled (|M|) copuling matrices are listed, but no information about deformation potential, which is the one I need. How can I print the results of deformation potential? Could you please help me? Thank you very much.
