abstract = {This is Part II of two closely related papers, where we
show that the strong repulsive interaction caused by
specifically adsorbed anions leads to a failure of the
nearest-neighbor Ising model to describe structures on
electrode surfaces. In this part, an analytical form of the
step diffusivity is derived in terms of nearest and
next-nearest neighbor interactions for steps with a mean
direction along 〈110〉〈110〉 (the close-packed
direction). With the help of a further analytical expression
for the diffusivity of steps with 〈100〉〈100〉 mean
orientation a simple scheme is developed whereby the nearest
and next-nearest interaction energies can be extracted from
the experimental values for the diffusivity along the
〈110〉〈110〉- and 〈100〉〈100〉-directions. The
method is applicable to repulsive and attractive
next-nearest neighbor interactions, both for surfaces in
vacuum and in contact with an electrolyte. An example is
presented in Part I, where we apply our approach to Au(100)
in Br--, Cl-- and SO42—containing electrolytes.},
