    Ge/Si islands in a three-dimensional island crystal studied by x-ray diffraction

  • Original language description

    An analysis of coplanar high-angle x-ray-diffraction data was performed and structural information on buried Ge islands forming a 3D island crystal was obtained. We have demonstrated that the combination of an analytical solution of the equilibrium equations of linear elasticity with kinematical scattering theory can be used to simulate the experimental x-ray-diffraction data. The strain state in the buried islands and their surrounding Si matrix was determined. The Ge content in the islands is found tobe on the average 40%, and the island shape does not change dramatically during capping.

    Studium třídimnzionálního krystalu Ge/Si ostrůvků RTG difrakcí

  • Czech description

    V článku je prezentována analýza experimentálních dat z měření na tří dimenzionálním krystalu Ge/Si(001) ostrůvků ve vysokoúhlé RTG difrakci. Prokázali jsme, že kombinace analytického řešení rovnic rovnováhy lineární elasticity a teorie kinematického rozptylu mohou být úspěšně použity k simulaci dat z RTG difrakce. Byly získány strukturní vlastnosti Ge ostrůvků, deformace krystalografické mřížky v ostrůvcích a okolní Si matici. Ukázalo se, že po zarostení do Si matice klesla koncentrace Ge v ostrůvcíchna 40%, jejich tvar se však výrazně nezměnil.
