[CPMD-list] artificial atoms

[Dai Ling]

Dear Sirs:
 
Is it possible to create artificial atoms in CPMD? For example, I want
to cut a B-terminated surface from cubic BN bulk, the bottom layer is
N-terminated which will be saturated with hydrogen atoms (H). As BN
surface is polar surface, so I hope the H atoms for situration have 3/4
electrons and the mass is 20. Could you please kindly advise us how to
implement it?
 
Thanks!
