Streaks in the buffer layer of wall-bounded turbulence are tracked time to study their life-cycle. Spatially and temporally resolved direct numerical simulation data is used analyze strong wall-parallel movements conditioned low-speed streamwise flow. The analysis streaks shows that there a clear distinction between wall-attached detached streaks, former can be further categorized into containe...

In this study, we investigated reactive diffusion at the interface between a Cu back electrode and ZnSnP2 absorber, which ohmic behavior was previously confirmed by appropriate annealing. Cross-sectional observation of Cu/ZnSnP2 revealed that Cu3P formed along surface after It also found epitaxially beside with lattice-mismatch less than 0.5% electron diffraction around Cu3P/ZnSnP2 consideratio...
