Abstract
We calculate the surface density of state of iron based LaFeAsO1 - x Fx superconductor. The gap function is obtained microscopically by solving the Eliashberg equation in a 5-band Hubbard model with the random phase approximation (RPA). Although the gap function has a sign change between Fermi surfaces, we cannot find zero bias conductance peak for [1 0 0] and [1 1 0]-oriented interface.
