Interatomic potential for Copper beryllium

Hello all,
I am carrying out simulation which consists of Copper (Cu) and Beryllium (Be) atoms. In particular i am using CuBe alloy in Be is 2%.
However, Interatomic potential is not known for Cu-Be.
As for now i am using
Cu-Cu : EAM potential (from literature)
Be-Be : Tersoff / ABOP (not sure)
Cu-Be: not known

Could you tell me which Interatomic potential will define the Cu-Be and Be-Be interaction.


That’s more a question for a literature search,

unless you get lucky and someone on the mail list knows

an answer.
