We demonstrate the selective area growth of GaN-(Al,Ga)N core-shell nanowire heterostructures directly on Si(111). Photoluminescence spectroscopy on as-grown nanowires reveals a strong blueshift of the GaN band gap from 3.40 to 3.64 eV at room temperature. Raman measurements relate this shift to compressive strain within the GaN core. On the nanoscale, cathodoluminescence spectroscopy and scann...
This study presents a comprehensive evaluation of Equal Channel Angular Pressing (ECAP) processing on the structural evolution and mechanical properties AA2xxx aluminum alloy. Finite element analysis (FE) was used to deformation behavior billets during in addition investigate strain homogeneity longitudinal transverse direction. Billets AA2011 alloy were processed successfully through ECAP up 4...
First, we prove that the BMO condition by John–Nirenberg leads in natural way to asymptotic homogeneity at origin of regular homeomorphic solutions degenerate Beltrami equations. Then, on this basis establish a series criteria for existence equations whole complex plane with infinity. These results can be applied fluid mechanics strongly anisotropic and inhomogeneous media because equation is f...
