英文摘要 | The composition and stain distributions in the ingan epitaxial films are jointly measured by employing various x-ray diffraction (xrd) techniques, including out-of-plane xrd at special planes, in-plane grazing incidence xrd, and reciprocal space mapping (rsm). it is confirmed that the measurement of (204) reflection allows a rapid access to estimate the composition without considering the influence of biaxial strain. the two-dimensional rsm checks composition and degree of strain relaxation jointly, revealing an inhomogeneous strain distribution profile along the growth direction. as the film thickness increases from 100 nm to 450 nm, the strain status of ingan films gradually transfers from almost fully strained to fully relaxed state and then more in atoms incorporate into the film, while the near-interface region of ingan films remains pseudomorphic to gan. |
