In this thesis, dislocations and other crystal defects of compound semiconductor materials were characterized by synchrotron radiation X-ray topography (SR-XRT) and X-ray diffraction (XRD).Crystal defects in GaAs structures grown by hydride vapor phase epitaxy were characterized. GaAs diode components were processed of epitaxial p-i-n structures. The response of the diode components was measured with fluorescent X-ray photons. Results of SR-XRT measurements were compared to the electrical characteristics of GaAs detector diodes. Medipix2 read-out circuit compatible GaAs sensor was processed of epitaxial GaAs wafer. The sensor was bump bonded to the Medipix2 read-out circuit. The response of the manufactured radiation detector was measured ...
