Research Abstract |
We study the atomic and electric structure on the (101) and (100) surface of beta-FeSi2 by ab-initio calculation using the projector augmented wave method (PAW). The cohesive energy calculated with the slab model show that the structure Si layer biased in the surface is stable. The simulated STM images indicate that the charge in the neighborhood of Fermi level concentrated on Fe-Si bonding.Also, Ru films formed by this new process have (002) preferred orientation and Cu (111) was formed by plating. This result corresponded to the tendency predicted by ab initio calculations.
