Abstract :
The authors study the presence defects in a GaN thin film, which was grown on Si (100) substrate using molecular beam epitaxy (MBE). The optical, structural and electrical characteristics of the sample are observed via photoluminescence (PL), X-ray diffraction (XRD), scanning electron microscopy (SEM) and Hall-effect measurements. From the measurements, the presence of cubic inclusions and the behavior of the defect in the sample have been identified.
