Resume: In this study, we examd. individual bismuth telluride nanowires (NWs) electrodeposited in polycarbonate membranes (PCM) used as sacrificial templates. It has been demonstrated that the compn. of Bi2Te3 is controlled by the electrodeposition conditions, e.g. the applied potential. High-resoln. transmission electron microscopy (HRTEM) shows that the av. grain size of NWs increases with increasing Te content. Our results also reveal that the electrodeposited bismuth telluride NWs are n-type, and their elec. cond. increases with increasing Te content. These NWs also demonstrated a max. power factor of 195.8 mW/m·K2 for the Te-rich NW (d = 162 nm) at 300 K. [on SciFinder(R)] Equipe: Département CP2S : Chimie et électrochimie des matériaux |

The scanning electron microscope images showed the formation of craters with cones, holes, corona, and other exotic structures. The atomic force microscopy images allowed evaluating the depth and height of these complex structures together with the chemical information as determined by NanoSIMS imaging. The plasma impacts locally removed the mono-layer and the bilayer down to the bare silicon substrate. In order to convert the acquired NanoSIMS images into a true three-dimensional distribution of the analyzed species, the SIMS images are overlapped with the corresponding atomic force microscopy images of the same probed area. This analysis method allows a visualization of a complex 3D structure and helps understand the formation mechanisms of the streamer impact. Copyright (c) 2014 John Wiley & Sons, Ltd.
