Scaling studies of nano dots formed on InP(111) surfaces via MeV implantation.
The scaling parameters have been studied here for InP(111) surfaces that evolve after implantation with MeV ions. The surfaces show the development of nano pattern and kinetic roughening. Growth exponent beta, roughening exponent alpha and the characteristic wavelength have been studied here at several fluences. Scaling parameters suggest that the surface evolution can not be explained by linear Bradley Harper model or by Kuramoto-Sivashinsky model alone.
