This paper reports on optical measurements of GaP nanowire (NW) arrays with thin nanocrystalline ZnO layer. The GaP core was prepared by metal organic vapor phase epitaxy (MOVPE) and the ZnO shell by RF sputtering by different sputtering conditions. The NWs were grown from Au seeds created from very thin Au layer deposited on top of GaP substrate. Reflectance of different NWs structures covered by ZnO coating was measured in angular dependence in wide range of angles and compared. We experimentally show the reflectance suppression of the ZnO coated NWs in the wide range of angles.
