[Pw_forum] Can anyone help me with GaN p type doping

[Daya sagar]

Hi,

  I am working on GaN nanowires. Can anyone please let me know which material should be used as p type dopant for GaN. I tried using Mg and Si as p type dopants but they seem to create bonding between 2 Ga atoms and create bands in the energygap. 
I would be really thankful if anyone can help me solve this problem.

Thanks.

Regards,
Sagar.
