If a single atom attaches itself to a flat close-packed interface it will raise the interfacial free energy.

If a single atom attaches itself to a flat close-packed interface it will raise the interfacial free energy. Correct Answer True

If a single atom attaches itself to a flat close-packed interface it will raise the interfacial free energy and will therefore tend to detach itself again. It can thus be seen that continuous growth at the above type of interfaces will be very difficult which means the mobility and the accommodation factor will be very low.
