Our results show that the development of compositional stress during diffusional relaxation can explain the preservation of the observed short wavelength compositional. The thermodynamics of stressed crystals that can change phase and composition is examined with particular attention to hypotheses used and approximations made, bulk and surface. Our results show that the development of compositional stress during diffusional relaxation can explain the preservation of the observed short wavelength compositional.
Here, we determine how the instability is modified in an alloy film by. The measured stresses were shown to be compositional dependent and spanned both compressive and tensile stress states. Our results show that the development of compositional stress during diffusional relaxation can explain the preservation of the observed short wavelength compositional.
