[QE-users] Band Structure of Armchair CNT

[ALVANH ALEM PIDO]

Hello,

I have calculated the band structure of (9,9) CNT by defining it as a
tetragonal crystal in reciprocal space. I found that only the Gamma-Z is
significant while the other paths such as gamma-X-M-..so on are showing
flat bands. Is this normal? Thank you.
