Resumen en inglés | Epitaxial single crystal films of Ge, with thickness from 0.2 to 2.4 µm, were grown on GaAs (001) by rf sputtering. These layers were characterized by High Resolution X-Ray Diffraction (HRXRD). Measured rocking curves show that pseudomorphic samples with good structural quality can be obtained by this growth technique. Asymmetrical reflections (115) and (-1-15) are used to determine the in-plane and in-growth lattice parameters of the grown films. From the behavior of these parameters and Ge diffraction peak broadening, with the layer thickness, an experimental value of 1.8 µm is obtained for the critical thickness of Ge grown on GaAs (001) |
