| Research Abstract |
Structural inhomogeneity is one of the issues in the self-organization of semiconductor nanostructures. To clarify the mechanism of structural inhomogeneity, we have developed an X-ray optics allowing for one-micron-focusing of X-rays at a synchrotron beamline designed for in situ X-ray diffraction during molecular-beam epitaxy. Through investigation of individual structures of semiconductor nanowires, micrometer-sized crystals of gallium arsenide grown on patterned silicon substrates and dislocations of indium gallium arsenide films by micro-beam X-ray diffraction under in situ conditions, we have obtained knowledge useful for the control of semiconductor nanostructures.
