Electrospinning successfully grew zinc oxide (ZnO) nanofibers onto porous silicon (PSi). The ZnO sprayed solution was prepared from the mixture of zinc acetate hydrate dissolved in distilled water and polyvinyl alcohol (PVA) precursor with a ratio of 1:3 wt. %. The obtained ZnO fibers sample was subsequently annealed at RT, 100°C, 200°C, and 300°C. ZnO polycrystal with hexagonal wurtzite structure formed on PSi substrates at the orientation of (002), (102), and (110). SEM characterization revealed that the average diameter of fibers decreased with the increased annealing temperature due to the decomposition of the PVA and acetate groups. The ATR-FTIR spectral showed the presence of a metal oxide bond group owing to ZnO characteristics on the PSi surface. © Published under licence by IOP Publishing Ltd.
