Ελεγχόμενη ανάπτυξη και τροποποίηση διατεταγμένων μονοδιάστατων νανοδομών ως μια πλατφόρμα για εφαρμογές στη μετατροπή ενέργειας, στη φωτοκατάλυση και στους αισθητήρες αερίων ρύπων
Exploration of the nano-scale regime has opened new opportunities for
science and technology on the basis of unconventional properties of
nano-structured materials. Amongst these, one-dimensional structures (1-D)
such as semiconductor nanowires (NWs) show a consistent potential for
applications and have received significant attention as they combine the
nano- with micro-scale dimensions that enables exploitation of a number of
effects. ZnO has emerged over the last decade as a key system in
nanotechnology and a platform for applications owing to its optical and
electronic properties, as well as because it exhibits the most abundant
configurations of nanostructures that one single material can adopt. The
current talk summarizes our recent activities on the controlled growth of
ZnO NW arrays and core-sheath hybrid structures, with the desired
morphology (aspect ratio) using predominantly wet chemistry and CVD
synthetic routes.
Selected applications of ZnO NW arrays for energy conversion (solar cells,
H2 evolution), photocatalytic waste-water treatment, gas sensors and in
nano-photonics (SERS substrates) will be reviewed.
