Study of ion beam synthesized nanostructured PbTe surface

▸ Synthesis of oxygen free PbTe nanostructure by ion beam mixing. ▸ Atomic force microscopy and scanning electron microscopy are used to characterize the structures. ▸ Unstable growth and rapid roughening of surface is observed under SHI irradiation. ▸ The values of exponents obtained from the experiment are different from those predicted by universality classes.
