Thanking you sir,
  i want to build heavely doped pn junction by using of ATK12.8.1, then how much charge i suppose to give in p type & n type ?

General Questions and Answers / doping in graphene

« on: February 18, 2013, 14:13 »

sir
Glad to use AtK tool trail version, I want to build graphene pn junction of 30 nm size.

 Project is :

                      15 nm i need to dope with P+ atoms

                      15 nm i need to dope with n+ atoms

 Problem is :

                      1.  Graphene is purely conductive and Carbon atoms in the sheet did not have any free electrons to get paired with dopant atoms.

                      2. I want to know is doping mean replacing of single carbon atom with dopant atom?Huh??

                      3. If it is so in what concentration i need to replace carbon atoms with dopant atoms?Huh?

 
         Please help me with the above questions. It will be so helpful to me.
