... part. Conclusion The origin of cracks in GaN film grown by MOCVD- HVPE system has been an alyzed by SEM, HR-XRD, Raman, and CL. The stress distribution was obtained by cross-sectional Raman spectra. According ... The stress is affected by lattice mismatch, coefficient of thermal expansion mis- match, islands coalescence, grain growth, and gas impurity [17]. Thermal strains induc...

... 2. As stated above, InN NWs have been grown by a variety of methods [10–14]. In particular, InN NWs have been obtained via the reactive vapor transport method using high purity In and NH 3 at ... also grown directly on quartz and Si(001). The InN NWs grown at the optimum temperature i.e., T G = 600 °C on silicon and quartz are characterized by the hexagonal wurtzite structure confi...
