[DFTB-Plus-User] ASE with DFTB

[Abid Channa]

Hi Dear Junmian Zhu ,
Thanks for your prompt response. Basically I am dealing with crystals and surface calculations using DFTB+ along with ASE. As far I know,  the parameters available at DFTB+ website for Au (Gold) are for Au-clusters. 
I am using same Au cluster parameters for my crystal calculations in order to optimize the properties like Lattice constant, bulk modulus , elastic constants etc before starting calculations with surfaces. I'm not getting good agreements between experimental values and these parameters.
In short, My query is that" Any body knows the Au crystal parameters, not cluster parameters because these are already available at website?. or any one else who is working on crystals and surfaces using DFTB + code ?.
Thanks for reading my detailed query.
Best,

Dear Abid Ali, 
 
  
 
I have some experience with using ASE with DFTB+ code. Please feel free to ask me relevant questions and I will try to answer.
 
  
 
Thank you,

Hi Guys,
 
  
 
I just joined DFTB mailing list today. Is any one here who is working withASE (Atomic simulation Environment) using DFTB+ code.
 
  
 
I have query about surface calculations using DFTB parameters with ASE package.
 
  
 
Best,
