etal oxide materials are the focus of many researchers

being often used due to their abundance in nature

and low environmental impact. Topics have been going

recently towards the nanoscale because of the diverse,

yet unique characteristics given by the low dimensions

together with reducing the amount of employed

material. The particular properties of nanowires make

them suitable for applications such as high sensitivity

sensors, catalysis, power generators, etc. ZnO nanowires

have a high surface to volume ratio and exhibit special

electrical properties with applications in field effect

transistors, diodes. However, they are interacting with the

surroundings, even dissolving in the presence of more

acidic environment and in order to affect this occurrence

a shell material is proposed. The ZnO nanowires are

prepared by thermal oxidation in air at 500°C on zinc

foils and on top of it a thin layer of CuO is deposited by

magnetron sputtering. The structural, morphological,

optical and electrical properties of the prepared nanowires

are investigated before and after the shell deposition.

Moreover, the nanowires were transferred in alcohol and

single nanowires were contacted using photolithography

and e-beam lithography and their electrical response was

measured at various temperatures. Differences between

the bare ZnO nanowires and their core-shell counterparts

are evidenced.
