AB  - Structural and optical properties of ZnOeGaP coreeshell nanowires were studied by means of electron
AB  - microscopy and microphotoluminescence. A thin ZnO shell layer was deposited by RF sputtering on GaP
AB  - nanowires, which were grown on GaP (111)B substrates under vapoureliquidesolid mode by MOVPE.
AB  - The SEM and TEM characterization showed that the ZnO shells fully covered the surface of the NWs from
AB  - top to bottom. Each GaP NW core is composed of many well-defined twinned segments with the planes
AB  - of twinning oriented in perpendicular to the growth direction. This was contradicted in kinked GaP NWs:
AB  - their growth direction was initially perpendicular to the twinning planes, but once the NW had kinked, it
AB  - changed to lie within the twinning planes. The ZnO shell deposited on the GaP core has a columnar
AB  - morphology. The columns are inclined at a positive angle close to 70 with respect to the GaP growth
AB  - axis. All observed columns were tilted at this angle to the growth direction. Micro-photoluminescence
AB  - study showed that thermal annealing improved the quality of the ZnO crystallographic structure; the
AB  - annealing made observable the photoluminescence peak related to the band-to-band transition in ZnO.
