GEAM INVESTIGATION OF THE INTER-ATOMIC POTENTIAL STRUCTURE OF RHODIUM (RH) AS FCC METAL HAVING ELASTIC CONSTANT WITH BOTH (C_12> C_44 ) AND (C_12> C_44 )

The generalized embedding atom method GEAM, a model of the EAM designed by [1] was applied to study the surface energy status of Rh as fcc metal having both positive and negative Cauchy’s discrepancy in our preceding papers. To further test the effectiveness of the model’s parameters flexibility, this work has investigated the behaviour of the lattices of Rh by comparing the inter-atomic pair potential of both status Rh with that of [2] using the values predicted in our preceding work.
