Dear QuantumATK expert,
  Recently, I optimized  a structure of armchair MoS2 with edge hydropassovation. But  some bonds bteween S and Mo break in the final optimized structure.  I tried to change some parameters and then calculate, but the bonds are still broken. I don't know what's wrong with my script. Please give me some guidance.
  My script and the opyimized structure in the attachments.
  Thank you!

General Questions and Answers / spin-polarized IV curve
« on: August 23, 2018, 04:39 »
Dear sir,
 I am working on a defective system depending on spin-polarized. The band structure shows spin  splitting phenomenon. What's more,  the band gaps of spin up and spin down are different. However, the IV curves of  spin up and spin down are same. I want to know why the currents of spin up and spin down are same.
 Looking forword to your replies!

General Questions and Answers / Band structure
« on: July 10, 2018, 16:21 »
Dear sir,
I meet a problem when I calculate the band structure of a supercell with different lattice type. For a structure, when its lattice type is unit cell , I can calculate the band structure. However,  when  the lattice type is changed into hexagonal, all the calculated energy band are straight and parallel. Please tell me what caused this phenomenon and how can I get the correct band structure? Thank you!

Dear professional,
    I use the Virtual NanoLab 2016.4 software since last year and it  always works well. However,  the  Virtual NanoLab 2016.4 can not calculate the simulation results  recently. It is caused by the licenses error, but I do not know how to solve it. The detailed errors are as follows:
License Error: (Internal: 501 Feature: ATKPython)

[NETWORK] 6200@io02 - (Err: 15) Unable to connect to license server

License configuration (environment variables):
---------------------------------------------------------------------------
QUANTUM_LICENSE_PATH = '6200@io02:/gpfs1/
