Abstract
Extended X-ray absorption fine structure spectroscopy has been used to investigate the microscopic structure of InGaAs pseudomorphically gro wn on a [001]GaAs substrate. The measure is restricted to the quasi-su rface region of the epitaxial growth by means of the glancing-angle te chnique. The results show that the strain is accommodated by bond-stre tching and bond-bending and that the lattice expands in the growth dir ection within the limits previewed by the elastic theory.
