Penta-graphene nanoribbon

[Trung Phuc]

Hello administrators!
I am a new user of quantumwise. After reviewing your previous posts about how to create penta-graphene. I tried to make penta-graphene ribbon like this paper (attached below). Personally, I think my outcome (attached below) looks not bad. However, I had 2 problems:
+ Could not passivate one carbon atom with one hydrogen atom.
+ Could not repeat this unit cell to obtain a penta-graphene ribbon.
Thank you so much for your attention!

Dear Trung Punc,
please attach also the ATK Python script with the structure you have built. Makes it easier to help you...

Hi Jess!
Thank you for your suggestion. Here is my structure. I tried to color it to make it easier to see but the color disappeared after saving.
I  look forward to see your advice.

1) You should use the recipe on https://quantumwise.com/forum/index.php?topic=5329.msg23011#msg23011 to first create penta-graphene, then remove the appropriate C atoms  to create ribbon without repeating the cell.
2) Use the Coordinate Tools --> Custom Passivator with SP2 hybridization to passivate with only 1 H atom.

You should probably also swap a few axes to align the ribbon along C.

Thank you so much, Jess!
Your advice is very helpful to me. In addition, your other answers in this forum are so great. Keep doing your job well. I will practice more and more.
You spent a lot of time helping me. Hope you be healthy and happy.
All the bests,
